1 WELCOME to the LTER Data Co-op with PASTA (Provenance Aware Synthesis Tracking Architecture) All Scientists Meeting 2012 Your source for LTER data

2 What is the Co-op? The foundations of the Co-op have been laid to provide accessibility to LTER Data with cooperation (hence the Co-op) from LTER Scientists and the Network Information System You (as an LTER Scientist, Information Manager, Grad Student) are a shareholder in the Co-op The LTER Data Co-op will open for business in December 2012 with core functionality provided by the Provenance Aware Synthesis Tracking Architecture (PASTA) All Scientists Meeting 2012

3 The goals of the Co-op Producers (scientists and others) harvest their data into the Co-op for consumers to use. Consumers (researchers, other scientists, graduate students, educators, the general public) go to the Data Portal to find information about various ecological sites and conditions. Publication of data is the end result and rather than dollar bills exchanging hands, recognition is the currency for the Data Co-op’s transactions. The more data in the warehouse, the more recognition its members receive All Scientists Meeting 2012

4 Where can I find the new Co-op? All Scientists Meeting 2012 The Co-op is located at portal.lternet.edu

5 The highlights… How can I contribute data to NIS (the Co-op)? How do I find data in NIS (the Co-op)? How does the NIS enable Network synthesis? How will the NIS maintain data provenance for derived products? How can I track who is using my data? All Scientists Meeting 2012

6 The highlights… How can I contribute data to NIS (the Co-op)? How do I find data in NIS (the Co-op)? How does the NIS enable Network synthesis? How will the NIS maintain data provenance for derived products? How can I track who is using my data? All Scientists Meeting 2012

7 How do I contribute data to NIS? All Scientists Meeting Select the tools button to manage your data packages within PASTA 2. The NIS recommends always Evaluate your data prior to Harvesting. 3. Select Evaluate Data Packages

8 Evaluating data packages 4. Select Browse to find your xml document. 5. Once your xml document is listed in the file box, select the evaluate button 6. A Data Package Quality Report is generated. One of the columns within the report is status – this status is what’s important in this report: valid, info, warn, error. 7. Once all the errors are cleared, your xml is good to go for Harvesting. All Scientists Meeting 2012

9 Harvesting data packages Go back to the tools page and select Harvest Data Packages link. If you haven’t logged in prior to this point, you will need to complete your login to gain access to the Harvest functions. All Scientists Meeting 2012

10 Harvesting data packages On the Harvest page, data packages can be evaluated prior to being inserted. Note: Batch harvesting is available. A warning message will appear to indicate that the batch harvest may take some time. To view your reports, a link is provided on the tools page. All Scientists Meeting 2012

11 Viewing Harvest Reports Select the View Harvest Reports link In the Summary Table, the batch of xml files is listed. If you harvest 100 xml files, all 100 packages will be listed in the table. All Scientists Meeting 2012

12 The highlights… How can I contribute data to NIS (the Co-op)? How do I find data in NIS (the Co-op)? How does the NIS enable Network synthesis? How will the NIS maintain data provenance for derived products? How can I track who is using my data? All Scientists Meeting 2012

13 How do I find data in the data portal? 1. Select the Discover button 2. Choose from the listed options All Scientists Meeting 2012

14 How do I search PASTA for information on biomass? Basic and Advanced Searches can be done without logging in The Basic Search searches the dataset title, abstract, and keywords Just type in your search term and select the search button. All Scientists Meeting 2012

15 Biomass – Simple Search All Scientists Meeting 2012

16 Biomass – Selecting a data package Package Identifier: knb-lter-arc Selecting the link will bring up the Data Package Browser All Scientists Meeting 2012

17 Biomass – Data Package views available In the data package selected; knb- lter-arc , PASTA shows four separate available documents. One Metadata document Two Data documents (in this case the two documents contain the same data, one is in a comma separated format and the other is an Excel file format) The data package browser also shows the Quality Report for the package. All Scientists Meeting 2012

18 Advanced Searches The advance search functions of PASTA allow for a variety of searches, including searching by Spatial criteria. Subject, Creator/Organization, Temporal Criteria, and Taxonomic Criteria can also be used in an Advanced Search All Scientists Meeting 2012

19 The highlights… How can I contribute data to NIS (the Co-op)? How do I find data in NIS (the Co-op)? How does the NIS enable Network synthesis? How will the NIS maintain data provenance for derived products? How can I track who is using my data? All Scientists Meeting 2012

20 How does the NIS enable Network Synthesis? Subscriptions are used to automate workflows. Workflows can be basic - # of updates or Workflows can be advanced – create derived data products Users can subscribe to package updates and to package inserts Users must be an LTER member and be logged in to subscribe to events All Scientists Meeting 2012

21 Subscribe to events All Scientists Meeting From the tools page, choose Subscribe/Review/Test/Delete 2. The Event Subscription page contains four sections: Subscribe, Review, Test, and Delete 3. The packageId used for this demonstration is knb-lter-lno.4128

22 Reviewing existing Subscriptions All Scientists Meeting 2012 So you know you created a subscription but you are not sure what number it is. In the Review box, simply select the review button.

23 Testing an existing subscription Want to make sure that subscription you just created works? Put the Id # (remember in Review we retrieved our list of subscriptions?) in the SubscriptionId field and select test. All Scientists Meeting 2012

24 The highlights… How can I contribute data to NIS (the Co-op)? How do I find data in NIS (the Co-op)? How does the NIS enable Network synthesis? How will the NIS maintain data provenance for derived products? How can I track who is using my data? All Scientists Meeting 2012

25 How will the NIS maintain data provenance for derived products? Ties derived data to original data – provenance chaining When users create a synthetic or derived data product, they can copy a portion of the original metadata into the new derived data’s metadata – thereby maintaining the lineage of the new data. On the tools page, select Provenance Viewer All Scientists Meeting 2012

26 PASTA Provenance Viewer Type your packageId (knb-lter-nin.1.1) into the field on the page and select view All Scientists Meeting 2012

27 The highlights… How can I contribute data to NIS (the Co-op)? How do I find data in NIS (the Co-op)? How does the NIS enable Network synthesis? How will the NIS maintain data provenance for derived products? How can I track who is using my data? All Scientists Meeting 2012

28 How can I track who is using/viewing my data? Information viewed/downloaded within the LTER Network Data Portal is stored in the Audit logs and is searchable. Select the tools button to go back to the tools page. Under Review PASTA Audit Reports, select the link Data Package Audit Reports. Let’s look at who has been viewing data package knb-lter-nin.1.1 in PASTA. All Scientists Meeting 2012

29 Who’s been looking at my data? On the Data Package Audit Report page, the package ID is a mandatory field. Enter knb-lter-nin.1.1 as the Package ID. Leave the remaining fields empty. All Scientists Meeting 2012
