Lewis,

  Sorry for the delay in getting back on this...  traveling.



  I've not seen this paper but I would love too.  Alas..  being part of a non-profit we don't subscribe to any publisher access.  Could you DM me a copy of the paper in slack?



Done!



With respect to the prov challenge.  I guess there are two "ideas" there that connect to the working group developments.  One would be the "Connect with CDF" you referenced (https://esipfed.ideascale.com/a/idea-v2/215365).   The connection would be that the CDF represents the data facility and provider community.   The connection between PROV and this facility metadata work really is around the concept of "publishing" which you brought up in the call.   CDF is a good way to engage with data publishers interested in these topics and some of whom have demonstrated a willingness to help test ideas.



We really need to be able to ease the burden on publishers of metadata and prov and also connect that publishing back to a value those providers can see.   Many facilities are already exposing metadata to be harvested by groups (like DataOne or others) and also information for archiving requirements.   To come to them with something like schema.org (or more directly JSON-LD wth vocs like schema.org, re3data, GeoLink, etc) and then also say "now also publish prov records" is going to be difficult.  Their first question is going to be "show me how doing this provides more return than the investment it takes to do it".



Can you add the above sentiment to the Idea? The more we have over there the easier it will be for us to progress discussion on the topic.



One key to this I think is also making that publishing as simple as possible.  That is way I am interested in the prov-aq work at W3C.    I put this into the idea collection at https://esipfed.ideascale.com/a/idea-v2/214284    Adam Shepherd and I are working on deploying some initial end points from our data repositories for this and also working up some simple testing clients too.   In retrospect that idea should really have been titled  "exploring simple prov publishing patterns for data providers".  Which may or may not be prov-aq.



My hope is that by making both JSON-LD based metadata and prov as easy to expose as possible to the data providers (or tools, or anyone) the "value" goal we have to reach initially doesn't have to be as high.     Then, once there, the tools and others can start to value add on those initial resources and we can start to see a sort of network effect kick in.



We have to get that first step easy though for people.



Look forward to talking more about all this at ESIP!



Take care

Doug

Hi Doug,
I wonder if you’ve ever taken a look at the following
http://dl.acm.org/citation.cfm?id=2962062
Also, with regards to the community PROV challenge, which of your existing concepts (https://esipfed.ideascale.com/a/idea-v2/215365 ???) currently aligns most closely with your presentation today?
I’m CC’ing SemTech community as I think this is a conversation which others will be interested in.
Thank you for the presentation. You guys are doing some excellent work.
Lewis

    Beth,
       I am presenting a poster on this this week at EarthCube All Hands  so your timing is good.   We have been able to get some good interest in this approach at this meeting.

    June 27th would be fine.  I would be more than happy to present.  With respect to abstract, please see the text at the end of this email and see if that works.  Let me know any edits or suggestions you have to it.  One could also include the link to the PDF of the poster as well in any announcement. [1]

    Take care
    Doug

    Abstract  (based on poster abstract)

    The EarthCube Council of Data Facilities (CDF) formed the Registry Working Group to review alignment of existing approaches to research facility description and discovery.  The involved parties include the EarthCube CDF, Coalition for Publishing Data in the Earth and Space Sciences (COPDESS) and the Registry of Research Data Repositories (re3data).

    The group is addressing:

    - Formalizing a set of repository parameters of interest to CDF members.
    - Reviewing the alignment of those parameters with re3data and COPDESS with the goal of schema extension. The plan is to leverage the re3data schema by means of community profile.
    - Developing strategies for a more structured common approach for CDF members to express/expose this information.
    - Developing a means to encode this schema in a machine readable format and bring forward a possible implementation for publishing and subscribing to this data.
    - Demonstrating the use of schema.org for publishing and accessing this data and explore gaps in this approach and recommend solutions.
    - Working with the re3data editorial board and governance on approaches to leverage re3data as a reference implementation for collecting and exposing this data.

    By providing a common pattern for facilities to expose links to existing work already completed in service and resource description documents (SWAGGER, OGC, THREDDS, etc.), a broader audience can be achieved. Furthermore, facility description through approaches like the re3data schema registry enhance exposure.

    Additionally, a lower barrier to entry, and a minimal maintenance burden are achieved through use of existing web-based architecture and best practices.

    These approaches are done by the working group with the reference EarthCube architecture in mind.   They are viewed as contributions along the path to addressing resource discovery and assessment goals of the architecture.

        Good morning Doug, Lewis, and Andrea,

        Doug, I put off scheduling your demo because we were catching up on
        agenda over-flow items and also needed to work on the ESIP summer
        meeting plans. But I think we could accommodate a demo at our next
        meeting, which will be June 27. (The July meeting will be cancelled
        because it occurs during the week of the summer meeting.) If June
        doesn't work for you, then maybe the August 29 meeting. Let us know what
        works for you. I'd like to advertise the presentation widely both to
        other ESIP groups, and maybe around NASA and NOAA and USGS, in order to
        get potential adopters of semantic technologies to start seeing what is
        happening in the world of semantics and how it can help them. So if you
        could write a small advertisement for your presentation (soon, if you
        want to do it this month), that we could blast out to appropriate
        recipients, that would be really helpful. Let us know what your date
        preference is. (If neither June nor August is good, we can do it in
        September, too.)

        Thanks,

        Beth
