--- PIT VC Jan 30, 2014 notes ---
Attending: Tobias, Tim, Larry, Tom, Ulrich, Mark P.
1) Higher-level concerns / architecture:
- the discussion in the Google doc (at least as it was beginning of this
year) did not really reflect the ideas in the architecture diagrams.
This has somewhat changed now with more focus on concrete API methods
and implementation. The small detail discussions and things in it about
concerns of higher layers are there to keep the more elaborate upper
layers supported, but this should not feature creep into the API.
- it was also agreed that looking again a bit back towards the use cases
and the architecture is a good idea and will help us to see whether API
methods are missing and whether it will work together as desired. At
least Tim and Tobias are going to look at the use case docs again and
coordinate this through the Google doc so we don't do redundant work.
2) Data Type Registries WG development and synchronizing:
- we discussed the role of the type registries, also in view of the
architecture diagrams and clarified some things. The registries are
essentially agnostic to what you register with them, so we can register
both profiles and types and perhaps other things like property types. It
seems that there will rather be a lot of registered entities than just a
- We will have to look at the information required to register a type
and see whether and how we are able to provide it without overloading
our own API methods.
3) Google doc status:
- edits are continuing, now with more focus on the later parts (API
methods and implementation). The doc needs some clean-up over time;
Tobias will take care of this.
- we did not have immediate suggestions for missing methods. The use
case analysis could reveal some gaps.
- we should do a Java API and a RESTful API, perhaps a Python API (in
this order of priority).
- the use case analysis could also point out requirements for the
- EUDAT connection: There was a recent call from EUDAT looking for
further partners. It was suggested that the WG (or better, the PID IG,
as the WG will be terminated) could be a candidate there. Questions are
what sort of status EUDAT expects from such an entity and what work is
involved. Ulrich can ask at an EUDAT meeting on Monday. We can also put
this on the agenda for the Munich meeting (24/25. Feb).
- The PIT WG roadmap: Current roadmap looks like that we should come to
a stable document around P3 so we can do the implementation over summer.
The implementation does not look like too much effort; CNRI may put this
even in the proxy server.
- However, we also need some instances populated to demonstrate the
functionality. DKRZ could provide some content, though that will be
biased towards Earth Science model data and the local use cases. An idea
is to use the EUDAT connection to get some input from EUDAT user
communities. This is however a process that must be initiated soon so it
is ready before P4.
