WISHI online meeting

June 4th (Thursday), 6:00-8:00 PDT (15:00-17:00 CEST, 13:00-15:00 UTC)

Draft agenda:

  • Identifiers, References, Paths, and Pointers

We are using URIs and URI references for many things. URIs are used both as semantic identifiers and as identifiers of resources that can be operated on. URI references, as well as CURIEs, are used in our specification documents. There also is a need to point into the insides of resources; we use JSON Pointers packaged into URIs to name elements of OneDM specifications. XPath has been widely used in the XML community to make such internal references into XML documents in a generic way, not necessarily depending on the structure of one specific instance. XPath is powerful to the level of being turing equivalent. While XPath now sports functions that operate on maps and arrays as they are used in JSON, in the wild, people are more likely to use a dialect of "JSON Path".

Where is this landscape of Identifiers, References, Paths, and Pointers moving to? What should be the guiding principles? Looking for contributions/positions.

  • Planning further meetings

Likely Future Agenda items:

  • Data definition (JSON Schema, DTDL)
  • DTDL in general
  • Further OneDM oriented
  • Implementation oriented ("Hackathon")

Timing: Move into OneDM-like slots (Thu/Tue 1800Z)? PDT-oriented (7 am = 1400Z, 8 am = 1500Z)?

For background, see the previous meeting notes.

WISHI on-line hackathon

April 9th (Thursday), 7:00-11:00 PDT (16:00-20:00 CET, 14:00-18:00 UTC)

We are planning to start with a short kick-off chat to plan the logistics, followed by 3-4 hours of hacking, before we reconvene to discuss the results. We will have a Webex session open during the hackathon for discussions. Focus of this hackathon is on tools and technologies for OneDM model interoperability, such as the “semantic proxy”, model translations, and protocol bindings.
