2. IBM Software Group | Rational software Purpose  Verify that RPE can consume data using the OLSC Reporting Specification 1.0  Scope  Defined by http://open-services.net/bin/view/Main/ResourceQuery#spechttp://open-services.net/bin/view/Main/ResourceQuery#spec  Main objectives  Validate query language  Validate automatic result set schema construction 2

3. IBM Software Group | Rational software Solution  The main features of the POC are:  Manual input of resource shape definition  Graphic query building  Automatic construction of result set schema  Request data from the source provider using the built query  The tool will be built as a standalone tool.  The tool will have a single UI screen to allow the user a global view at all times  allows an immediate validation of the query building and the construction of the result set schema  most bits of the POC can be immediately integrated in RPE  the POC can be used as a reference implementation as well as a simple test tool for providers. 3

4. IBM Software Group | Rational software Resource shape definition  Entered as XSD  The user will point the tool to an XSD file  Entered visually using a tree editor that supports adding nodes of type “element” and “attribute”  The resources will be of two types: list and simple. Is this needed?  Advantages  Sufficient to validate query building and result set schema construction  decouples the POC from the Resource Shape Definition  prevents hard coding the resource shape definition 4

5. IBM Software Group | Rational software Query Building  The user will define the query in the following way:  Define the oslc.prefix for the resource  define the oslc.select and oslc.properties values by selecting the appropriate nodes in the resource shape tree  (optional) type the oslc.where value in a text box  (optional) type the oslc.limit value in a text box  (optional) type the oslc.orderBy value in a text box  The tool will encode the request to valid URL syntax 5

6. IBM Software Group | Rational software Construction of result set schema  The tool will create the result schema based on the resource shape definition and the current query value  How is the oslc.prefix reflected in the result set? 6

7. IBM Software Group | Rational software Request data from provider  The user needs to define the URL where the query must be sent  ex: https://localhost:9443/testcasehttps://localhost:9443/testcase  The user needs to provide authentication information:  Credentials  Authentication type ( the POC will support only basic and form based authentication)  The user sends the request by clicking the “SEND“ button  The status and error information of the HTTP requests and responses are provided to the user  The result data is saved in a temporary folder and the link is provided to the user to open it 7
