12. RETAIL CUSTOMER

13. Object Identification Objects are instances of classes Objects need to be identified uniquely because – Data in a repository needs to be identified as to where it came from – Updates to data (for example from raw to validated) need to identify that it’s the same data that has been updated – Devices from which data originates often needs to be associated with the data – Devices need to be labeled multiple ways for various purposes – e.g. in a building topology (2 nd floor floodlight), in an electrical hierarchy (branch 2 load 3)

14. Master resource identifier issued by a model authority. The mRID is globally unique within an exchange context. Global uniqeness is easily achived by using a UUID for the mRID. It is strongly recommended to do this. The Name class provides the means to define any number of human readable names for an object. The name can be further attributed by a NameType and a NameTypeAuthority. IEC 61970 IdentifiedObject A simple string to identify the object.

15. IdentifiedObject mRID – usually a UUID that represents the object instance name – simple string to identify the object Name – a class that allows additional names to be used for the same object in different hierarchies. – different naming authorities may have the right to name devices for their own purposes – it is important to identify the naming authority and naming convention (type) – These must also be properties of the object to which they represent since it is the same unique object

16. ESPI Mapping of IdentifiedObject to Atom ESPI endpoints expose resources as described by Atom, IETF RFC 4287. Representations are identified as media type “application/atom+xml” ESPI namespace and types (“http://naesb.org/espi”) are used for objects in element espi:mRID is implemented by atom:id – UUIDs are used, as specified in IETF RFC 4122 espi:description is implemented by atom:title atom:published and atom:updated are used Associated objects use atom:link (rel=“related”) espi:name is implemented a resource.name

17. Solutions to Add Customer Account Numbers Add link Add Atom Extension Extend each Class with IdentifiedObject.name Make non- obfuscatedId

18. Account/Agreement Topology

19. Separation of PII containing Resource RetailCustomer from Subscription* Key New Resource Existing Resource Non-Resource Class *This data structure is to be developed on an aggressive schedule based on HelpDesk issue #83 and PAP10 NAESB Std REQ.18. No single API request can retrieve both PII and Anonymous data RetailCustomer UsagePoint EndDeviceAsset ServiceLocation PostionPoint PricingStructure Customer Agreement Authorization ServiceSupplier Normal ESPI Resources Subscription Anononymous EUI PII Containing information CustomerAccount

20. Model UsagePoints of RetailCustomer Location of premise Account ID Sub Account (SA) ID—Service Agreement / Account is name depending on utility Customer name, nickname (or short name) Address and info SDG&E provides only email address and UPID correspondence csv email and UsagePoint ID (Customer Obfuscated Key) MeterID ServicePointId Pnode LoadAggregationPoint, SubloadAggregationPoint Climate zone Account open date Account close date SA Open and Close date MDM Agent Id (who does meter read) ServiceSupplierId EnergyServiceProviderId (may be same as service supplier) Demand Response Provider May need list of Ids for service providers rather than explicit?? (0..* relationship{role, href}) Related assets ???? For example pool pump and pool pump participation in a program. Related programs ????

21. RetailCustomer API – GET.../resource/Batch/RetailCustomer/{id} – GET.../resource/RetailCustomer/{id} – … – GET.../resource/RetailCustomer/{id}/CustomerAccount/{id}/CustomerAgreement/{id} – GET.../resource/CustomerAgreement/{id} – GET.../resource/Batch/BulkRetailCustomerInfo/{id} Authorization – Scope string addition? RCInfo=AC where – A=Address included, C=AccountInfo included RCBulkId=123 for access to account info in bulk – Access tokens to access? Individual with access_token, bulk with client_access_token FB – Has RetailCustomer – Just one FB_4X with RCInfo – Has Additional Detail indicated by content of RCInfo

22. February Event – Preliminary Planning Celebrate: “Birth of the Green Button Ecosystem” – Testing and Certification Complete for DMD/CMD – UCAIug ITCA fully established – Initial Data Custodians successfully certified for DMD and CMD – Shower Successful T&C Adopters with Fame and Congratulations Venue and participation TBD in coming weeks

23. Best Practice Reading Quality Flags ReadingType.defaultQuality contains the default quality that applies to all corresponding IntervalReading data. IntervalReading.ReadingQuality.quality allows specific Intervals to override the default in ReadingType UsageSummary.qualityOfReading if present overrides default in ReadingType for those IntervalBlocks within the scope of the UsageSummary.billingPeriod If IntervalReading data are modified, DataCustodian should notify of this change so ThirdParty can retrieve the changes. If UsageSummary.qualityOfReading overrides the ReadingType or IntervalReadings, the IntervalReading qualities would change and a subsequent retrieval (not required) of the IntervalBlocks would come with the corresponding quality flag. The qualityOfReading flag for Usage Summary will indicate latest overriding quality of previously provided interval values corresponding to BillingPeriod dates The Default Quality (from ReadingTypeRef) for OverallConsumptionLastPeriod will indicate quality of total billed usage

24. Requests that are not inside authorization period Date of request April 5 Consensus: i – agree on 403 ii – agree on 403

25. FB3 - Core REST Services [R] GET resource/ApplicationInformation/{ApplicationInformationID} – [POS] Accept of valid request – [NEG] Reject by invalid ID – [NEG] Reject by invalid access-token – [POS] Results valid to schema and include required fields for OAuth and TP/DC interaction [C] GET resource/Authorization [C] GET resource/Authorization/{AuthorizationID} [A] GET resource/Batch/Subscription/{SubscriptionID} [C] GET resource/ReadServiceStatus POST: How to test for TP Notification – Trigger – Uses notification URI from ApplicationInformation – Expected content – at least one URI that can be GET’d?

26. Older or other slides Will build deck with new content over time.

27. FB_03 Core GB CMD Covers “core services”, resources and access control – atom:entry, atom:feed – GET, PUT, POST, DELETE (negative only) – ApplicationInformation – Authorization (feed) – Authorization (entry) – Subscription (entry) only available through batch/subscription – ReadServiceStatus (entry) – Access token expiration testing? – Authorization expiration? – Notification move to FB_39?

28. FB_03 Core GB CMD atom:entry / ApplicationInformation – Using required access token of R(registration_access_token) Verify successful GET and response contents (which subset of app info is required in the response?) – If it is required by OAuth2 dynamic registration it must be present – Other fields not derived from OAuth2? – i.e. ContactInfo used in the case of a failed notification to TP Verify negative response to PUT, POST, DELETE: 403 – forbidden – Using other access tokens(A,C) or none Verify negative response to GET, PUT, POST, DELETE: 403 – forbidden No token: 401 – unauthorized

29. FB_03 Core GB CMD atom:feed / Authorization – Using required access token of C(client_access_token) Verify successful GET and response contents (which subset of Authorization info is required in the response?) Verify negative response to PUT, POST, DELETE: 403 – forbidden – Using other access tokens (AR) or none Verify negative response to GET, PUT, POST, DELETE: 403 – forbidden No token: 401 – unauthorized

30. FB_03 Core GB CMD Authorization(C)- all fields(except error fields), some have of which have req. values Subscriptions(A) - feed with at least 1 UsagePoint ReadServiceStatus(C) – all fields with content of 0/1 – Using required access tokens Verify successful GET and response contents Verify negative response to PUT, POST, DELETE – TBD?: Using other access tokens or none Verify negative response

31. FB_39 Push Model – REST notifications Send Notification to TP – pre-test set up – DC needs to know TP stand-in URI (FB_33 could automate this?) – DC UT has manual “trigger method” to generate notification – ApplicationInformation – Authorization – Subscription Verify well-formed contents of the Notification Get the data (w/ correct access token) and validate the data [NEG] Test GET out of bounds and deferred response (should be moved to or is already present in other FB tests) – Authorization no longer valid (how?) – MOVE to FB_14 – Data no longer available (i.e. TP took too long for requesting the data) – SFTP error 2 ref to file that does not exist / REST GET error – Issue REST GET with wrong token (what token should the test use?) applies specifically to FB_39 to ensure notification data is secure [NEG] If TP Notify fails, verify by demonstration that failure was detected – TP is off-line

32. FB_34 SFTP for Bulk – Prerequisites Pre configured Authorizations Authorizations need bulk scope – Notification of Bulk sent to test harness i.e. sftp://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/Batch/Bulk/{BulkID} –Test harness retrieves data via SFTP –Validate the data Pass schema Must contain 1 feed w/ 1 or more entry(s) Verify there is a valid authorization for each entry and the scope of each authorization for each entry has BR=BulkId Use https://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/Authorization for list of authorizations to check againsthttps://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/Authorization –Is URI a pointer to a folder or a pointer to a file? –SFTP GETALL – could retrieve a set of files from a folder or –SFTP GET – single file

33. FB_35 REST for Bulk – Notification of Bulk Authorizations must be present Authorizations need bulk scope i.e. sftp://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/B atch/Bulk/{BulkID} –Test harness retrieves data via REST GET –Validate the data Pass schema 1 feed w/ 1 or more entry(s) Verify there is a valid authorization for each entry and the scope of each authorization for each entry has BR=BulkId Use https://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/ Authorization for list of authorizations to check against https://services.greenbuttondata.org/DataCustodian/espi/1_1/resource/ Authorization

44. FB_19: Partial update of data Is this requirement for upload role and not core data custodian?

45. [FB_37] Query Parameters Support published_min, published_max

46. [FB_40] Offline RetailCustomer Authorization Manual Creation of ApplicationInformation, Authorization(s)

47. ReadingType Attributes PG&E notices that their MDM uses various ReadingType attribute values that are not the same as those in the DMD test suite. Question – should meter data reflect the diversity of the meter system or the meaning of data conveyed to the ThirdParty Folks will look at their data and thinking further.

48. Interpretation of Quality Flags for UsageSummary, ReadingType, and IntervalReading ReadingType.defaultQuality contains the default quality that applies to all corresponding IntervalReading data. IntervalReading.ReadingQuality.quality allows specific Intervals to override the default in ReadingType If IntervalReading data or quality tags are modified, DataCustodian should notify of this change so ThirdParty can retrieve the changes. UsageSummary.qualityOfReading if present indicates that those IntervalBlocks within the scope of the UsageSummary.billingPeriod may have changed quality as well. Third Party may want to retrieve data again to see the revisions if any. The DC may indicate to the TP that IntervalBlock data has changed by sending a notification for the IntervalBlocks that changed.

49. Testing and Certification Issues Test Third Party role for testing DataCustodian Test accounts (how many ; real-or-not ; how much history?) Test Set up – Application Information How to put DC in reproducible state – reset? Minimum FBs to test – – FB_3, 13, 14, 19,37,39 Alternative – Test Environment that is same as the Live environment – Same Certs etc… – Does it need to be real data?

50. ElectricPowerUsageSummary Make general UsageSummary and deprecate ElectricPower one… Let query determine period not current/last How to rename fields to remove current/last ambiguity for past requests Determine what required fields might be and some possible new FB to support ecosystem interoperability Single Demand fields too limiting for modern tariffs.

51. UsageSummary Recommendataions Create new UsageSummary (which is NAESB REQ.18 name) Add new tags recommended by PG&E Retain all existing tags and make UsageSummary and ElectricPowerUsageSummary identical – but mark old one deprecated for backwards compatibility – new implementations will have to accept either Resource on input Revise descriptions of existing tags to make clear what goes with billing period etc. Provide documentation on how to interpret query parameters for GET UsageSummary

52. UsageSummary Use Cases I ask for summary today (with day later publishing) I ask for 3 months last year (query parameters?) Billing period is non-calendar John: I ask for an arbitrary period “roll-up” of consumption GET UsageSummary min=1/15/2014&max=2/28/2014&rollup=True – In PGE concept – you get 2 UsageSummarys – one for billing period January and one for billing period February – In John concept – you get 1 UsageSummary with totals for 1/15..2/28

53. Documentation Issues Do in GreenButtonAuthorization.docx section 2.4 – Use Cases for Authorization Termination (revocation) -- – DC-oriented control of termination process due regulatory requirements in Ca. Do in section 2.8 – Behavior of GET UsageSummary with query parameters

54. Service Request 83 – including Function Block for optional customer info (service point address, etc.) Requirements – UsagePoints of RetailCustomer – Location of premise – Account ID – Sub Account (SA) ID—Service Agreement / Account is name depending on utility – Customer name, nickname (or short name) – Address and info  from Lynn will provide more information – SDG&E provides only email address and UPID correspondence csv email and UsagePoint ID (Customer Obfuscated Key) – Current ESPI resources will never return PII – GET Subscription does not contain PII – Single Authorization covers entire Subscription and Authorization Scope – MeterID – ServicePointId – Pnode – LoadAggregationPoint, SubloadAggregationPoint – Climate zone – Account open date – Account close date – SA Open and Close date – MDM Agent Id (who does meter read) – ServiceSupplierId – EnergyServiceProviderId (may be same as service supplier) – Demand Response Provider – May need list of Ids for service providers rather than explicit?? (0..* relationship{role, href}) – Related assets ???? For example pool pump and pool pump participation in a program. – Related programs ???? Implementation – Resource Definition Probably multiple resources are good idea – REST service to exchange resource(s) GET only – Function Block(s) Wholesale vs Retail – Optionality vs Required – Possible Scope spec

55. For May 20 Topics Use Case for “verified for billing” – Added ServiceStatus – return data – Simple status or, outstanding batchlists – Consensus: Don’t really need this extension because the DC can determine if it wants to send a notification of what hasn’t been retrieved at its discretion. Revised Authorization document Use Case for Small ThirdParty / Mega ThirdParty … maybe another day in future revenue-quality data that is valid for billing purposes

56. Service Status Consensus: Don’t really need this extension because the DC can determine if it wants to send a notification of what hasn’t been retrieved at its discretion. As is in standard Enhanced to add current outstanding batchlist text 65535../espi/1_1/resource/Batch/Bulk/1?start-index=1&max-results=1000&published-max=2012-04-02T04:00:00Z&  published-min=2012-04-02T04:00:00Z 1

57. Authorization What happens when authorization changes – UsagePoints or period – When Authorization changes, place authorizationUri in notification to ThirdParty which can then re-establish its state

58. What can you negotiate with Scope? FBTerms – data content, CMD services ValueTerms – default durations and blocking, history length, subscription frequency (i.e. daily data cycle) ResourceTerms – specific resources available by api, bulkID assignments, bulkaccount Other?

59. Scope Negotiation DCTP HTTP Redirect with Scope={scope1} {scope2} … RC Logon Authorization request Scope={scope2} Authorization response Scope={scope2} access-token resourceUri authorizationUri referenceId … Oversimplified sequence diagram of Use Case #2 showing essence of scope negotiation

60. Scope issues Limit Scope to access-token and minimal exchange requirements Add list of UPs in a subsequent GET request – Could include UPs, optional location, additional data – We would define new resource that has this data Are there options? – FB_XX Minimum data – » UsagePoint – FB_XY Optional data » location Should it be a different namespace and XSD? – We need to make sure they are mutually exclusive – the usage and the PII containing data – Namespace and separate schema minimize the opportunity for comingling of data Single authorization with multiple UPs with different scopes – Don suggested that the scope is a union of capabilities. You need to get the data to see details – Jerry suggests scope be provided with UP?

A Couple of Use Cases Use Case 1: How to do Gas and Electric in one Authorization – An Authorization – Two UsagePoints – One Gas One Electric – Different Scope Use Case 2: CISR based Authorization – Customer logs in has id for utility website – Each login has multiple electricity accounts – Each account can be multiple usage points – Customer login id becomes obfuscated {referenceId} which can be used in REST Uris of the form: /espi/1_1/resource/RetailCustomer/{referenceId}/** – Authorization enables a subcriptionID and authorizationID which is (internally) correlated to the customer and the subselection of usagepoints

In the standard, only a few examples from the IEC standard were provided in a comment. Values that distinguish measurements of Wh, W, VAr, VA, gas, water, etc… are tested for in DMD if corresponding FBs are indicated. *Errors of data type corrected – value, cost, and currency all had deficient data types that were recognized early on *Representation of conversion factors from UTC to Local Time: LocalTimeParameters resource was added *Missing overallConsumptionLastPeriod was added to make ElectricPowerUsageSummary rational as a record of billing period consumption Support for OAuth 2.0: the second largest volume of changes to the schemas is in support of CMD (no impact to DMD) * Differences tested for in T&C

80. For February 25 John Teeter raises issue of path vs opaque URIs for REST services for individual and subscription resources – Does the uri give any indication of what will be retrieved or not?

81. Some URIs Found In GBDMD Files URI ::= protocol://hostname:port/datacustodian/espi/1_1/resource/  resource endpoint of the server

82. Opaque URIs – No need to test structure – No need to recognize structure in sw Structured URIs – Easier to recognize the links – Easier to validate what you are doing by looking at them – If I have interval block, I know all the possible URIs for that UsagePoint Possible Outcomes of OpenADE Discussion? – No structure, support opaqueness – Optional Structure, make structured URIs an optional Function Block – Required Structure, make structured URIs a requirement but allow some variability – e.g. User versus RetailCustomer –  Single Required Structure – defined structure based roughly on GreenButtonAtomLinks and Authorization documents

83. SFTP for Bulk Transfer Pertinent to the SFTP discussion are the concepts that each Third Party has a defined relationship with the Data Custodian. – For automated exchange of information about his relationship there is a special Authorization obtained in Use Case #1 (see the Authorization.docx -- http://osgug.ucaiug.org/sgsystems/OpenADE/Shared%20Documents/Testing%20and%20Certification/GreenButtonTestPlan/ref erenceMaterial/GreenButtonAuthorization.docx). http://osgug.ucaiug.org/sgsystems/OpenADE/Shared%20Documents/Testing%20and%20Certification/GreenButtonTestPlan/ref erenceMaterial/GreenButtonAuthorization.docx – We anticipate that when the Data Custodian has data available, it sends an asynchronous Notification to the Third Party. – This Notification provides URIs of note that it is assumed the Third Party will want to retrieve. For the purposes of Bulk transfer, this URI will be: – sftp://hostname:port/DataCustodian/espi/1_1/resource/Batch/Bulk/{bulkId} sftp://hostname:port/DataCustodian/espi/1_1/resource/Batch/Bulk/{bulkId} – where {bulkId} is a unique identifier assigned by the Data Custodian and the balance of the URI is presented in the ApplicationInformation resource that both parties share (contains all relevant URIs and data for interchange via OAuth etc…). The Third Party would then retrieve the bulk data by using an SFTP client with that URI. This is a straw man concept for discussion on the call. Its advantage is that it in harmony with overall architecture of the Green Button Connect My Data RESTful architecture and simply adds SFTP as a means of transfer when a large data set is to be returned. Used to Retrieve the data using SFTP protocols – How to initiate the SSH connection? – What is the role if any of the client_credentials authorization to control access to SFTP enabled resources? Discussion – – After authorization of TP, they use Pene test, so what is benefit of access-token? – sftp user:pw, user=, password= Summary – sftp://hostname:port/DataCustodian/espi/1_1/resource/Batch/Bulk/{bulkId} sftp://hostname:port/DataCustodian/espi/1_1/resource/Batch/Bulk/{bulkId} – sftp user:pw, user=, password=

There could be one or more terms in this list that express the granularity of notifications about resource changes. FBTermsThe function blocks supported (only data content FBs are listed) ValueTermsThese are parameterized terms IntervalDurationThis is the minimum default length of an interval in seconds (e.g. 900 for 15 minutes, 3600 for one hour, …) BlockDuration This is the length of a block that contains the intervals (based on enumeration of MacroPeriodKind in ESPI above as namedFrequency) HistoryLength This is the length of history buffer of records in number of Interval Blocks (e.g. 12 for a year if BlockDuration is “monthly”). Note: this is what the DataCustodian offers; however, the buffer may not be full for transitional metering systems; in these cases less data will be returned until the buffer is full. BulkAccountCollection Used where the DC wants to provide for the reporting of multiple UsagePoints in a single Subscription. The number of UsagePoints is represented by the value in the assignment statement – e.g. 4 UsagePoints would be BulkAccountCollection=4.

95. How to use BR=bulkID – relates to HD #61 Application Profiles – BulkID was proposed for large sets of authorizations – One account level authorization on top of service level accounts – how to do this Degrees of freedom we have now – can we cover – Subscription – 1 or more Usage Points Granularity of a customer authorization – BulkID “macro” for a large set of existing authorizations – Is there another degree needed?

96. Contributed by Jerry Yip Clarification/confirmation about ESPI standard: Does ‘shared resource key’ referenced in the NAESB Ratified word doc correspond to Access Token for oAuth? Yes: This is the access token in the new Oauth 2.0 paradigm. Formal Submission of Application Profile for bulk (vs. batch?) use case as part of GB/GBC Conformance Testing Plan Write up coming to test concept of BulkIDs Question: (options to address 1 Acct to many SA issue) - Does UUID correspond to usage point (1-to-1 relationship)? Is there passing of UUIDs (as resource terms in Scope section of GBAuthorization) during authorization sequence? (how would 3 rd Party know multiple usage points have been authorized via single oAuth sequence/login?) - Can multiple access tokens be issued (1 token per SA) per oAuth session? An Authorization is one access_token How does Third Party get to know the depth of data (how many Ups) are in the authorization Perhaps an extension of scope string to have numUPs? Request to consider scope selection screens at Data Custodian Portal instead of 3 rd party portal (Need customer to select SAs to share – only Data Custodian has that info) – also minimizes number of redirects (?) Customer info as optional functional block (atom feed) for authorization (sharing with 3Ps) John suggests – prep a large multi account data set and test against a reference sw implementation and measure. SFTP and Streaming, compressed and non-compressed method and compare.

99. Application Profile Per footnote 1, pg 20 of GBAuthorization.doc: – A “Web Customer” may actually manage more than one “Retail Customer” where “Retail Customer” is an actual “Customer Account”. Thus identifying the specific Retail Customer may be part of the scope selection on both sides. The scenarios in this section refer to the “Retail Customer” for simplicity. Suggest: new FB or Application Profile to properly capture this scenario [FB_31] Web Customer Manages Multiple Customer Accounts (OR: 3.9 Application Profile) For GBCMD, this FB/AP contains tests associated with a Web Customer accessing a Data Custodian’s Web Portal to manage multiple customer accounts. Upon log in to the Data Custodian’s Web Portal, the web customer can manage multiple customer accounts, for which each customer account can represent multiple usage points (for electricity and/or gas). This mostly impacts large agricultural and commercial customer accounts for which a single web customer can represent hundreds to thousands of individual usage points – imagine a franchise manager with multiple branch locations across a data custodian’s service territory. In this scenario, the Web Customer should have the ability to authorize, deauthorize and change scope on an individual “usage point” basis and optionally at the larger aggregated web customer or customer account basis. This includes the ability to perform one-time authorization of multiple customer accounts by a single web customer to third party, and any subsequent scope changes (whether on an aggregated or individual basis) – third party acknowledgement/communication of which customer accounts have been authorized, deauthorized or whose scope has changed needs to be determined. Notes: – Whether scope selection in this scenario should live on the 3 rd party portal vs. the Data Custodian’s portal needs to be determined as well. – Collection has one description or multiple? – What is the scope string for this use case? – Is there a need for a bulkId in this case (maybe not). – New Scope Resource Term= “BulkAccountCollection” – Scope= “FB=4,5,15;IntervalDuration=3600;BlockDuration=monthly;HistoryLength=13;BulkAccountCollection” 1/14/2014 – To allow the TP to know how many Ups are being provided, suggest Add to BulkAccountCollection a number of UsagePoints BulkAccountCollection=nnn
