Note

Reviewing the list below:

  1. Which features listed “By Summit” should we prioritize to try to release sooner?

  2. Are there any features we failed to list?

Tip

Meeting notes:

  • Data Standard support

    • Prioritize 5.2 for Tech Congress; many states are moving that direction right now.

    • Nice to have support for 4.0 as well, for pilot testing with vendors who have not updated to 5.x yet.

    • 6.0 preview is not useful from a pilot testing standpoint, since no one has an integration yet.

    • In 1.0, MSP’s would like to have support for multiple data standards at the same time: a single API deployment that can store both 5.2 and 4.0 data structures, with validation based on URL route. Allows for better cost optimization.

      • (warning) Parking lot: design discussion on mechanisms for supporting this. Initial proposal to prefer separate database instances for different Data Standard versions. Maybe tie DS version into the URL routing for instances?

    • Extensions should be the next priority after authorization; would like to have by Tech Congress if possible.

  • Profiles

    • Remove “dynamic” from the list to avoid confusion (same with “XML” on “XML Composites”).

    • Agree: must have for 1.0 and not mandatory for Release Candidate at Tech Congress.

  • Level 2 validation

    • Need to explain both types better when turning the table below into a formal document.

    • For streaming data, mention observability as well.

  • ETags

    • Some client integration may be looking for _etag in the body or the ETag header on POST requests.

    • For release candidate, should at least stub out a hard-coded value to prevent breaking client integrations.

      • (warning) Design note: we plan to calculate ETags based on hashing the _lastModifiedDate. This is relatively trivial. We should simply consider ETags as a must-have feature for the spring release candidate.

  • ODS-like Views

    • This discussion helped us recognize the value of talking about (at least) two stages of pilot testing: transactional vendor integration (via the API), and downstream reporting.

    • ODS-like views are intended to support the second stage of pilot testing. States could start testing a 1.0 release without the ODS-like views. Can potentially defer until after 1.0.

  • Core database storage

    • Correction, Education Analytics is today using Aurora for the ODS/API.

  • Change Queries

    • Current usage scenarios:

      • API-to-API synchronization via API Publisher

      • Assessment rostering

      • Enable Data Union (EDU) data warehousing.

    • We should consider this a must have solution, even if the streaming architecture can provide alternative synchronization patterns. Too many integrations would break without this.

  • Authorization

    • Ownership-based authorization and combined strategies are used in multiple states. Definitely a must have for 1.0, but can live without them for the release candidate.

This will likely be a compatibility layer to ease the transition for those who have built reporting solutions on the ODS database structure.

Is this required for state-based pilot testing? Can it be finalized after the 1.0 release?

Conceptually this should work, but we may need community help for testing these scenarios while the development team focuses on code-level features.

Demonstration

Tip

Meeting notes:

Ran out of time for the demonstration. The sequence diagram below shows the interactions for client credential management.

The demonstration was going to use this file which uses the REST Client extension for Visual Studio Code. Even without VS Code, the file should be easy to follow along with while replicating the API calls in another client such as Postman.

Design Questions

Tip

Meeting notes:

Ran out of time. Will keep these design questions for a future meeting.

What plans are there for error detection (i.e. dropped records) and correction?
