[12:06] <mpetyx>last telcon minutes approved
[12:08] <mpetyx> Topic: ashok discusses about what happened since the last telco and refers to the wiki page about the pg recommendation for working group
[12:09] <mpetyx> ... property graph is a well used and known data model. it is being used widely for a variety of applications
[12:09] <AndyS> https://www.w3.org/community/propertygraphs/wiki/Recommendation
[12:10] <mpetyx> ... people are moving into pg and getting more and more interesting on that and for this reason it needs to be standardised
[12:10] <mpetyx> ... thus, we could just start with the data model and later we go into details about the api and such details
[12:12] <mpetyx> ... using domain specific vocabularies like schema.org could be really useful on that direction
[12:13] <mpetyx> ... one default serialization needs to be also proposed for standarization
[12:15] <mpetyx> Topic: PhilA introduces himself
[12:16] <mpetyx> ... he express his scepticism about the proposal to W3C
[12:16] <mpetyx> ... if we start a working work who is going to use it and support it?
[12:18] <mpetyx> ... facebook, twitter and linkedin are not in the community group even though are mentioned in the description of the group
[12:18] <PhilA> I apologise for repeating my esteemed colleague from Budapest
[12:19] <mpetyx> Ashok, we contacted them but they are not currently in the group. They had some concerns
[12:19] <mpetyx> ... we got a lot of other guys from various companies
[12:20] <mpetyx> ... we could not convince facebook for example
[12:21] <mpetyx> PhilA, two of the companies mentioned are not W3C members.
[12:22] <mpetyx> Ashok, suggests that there is going to be a variety of implementations. Oracle is going to implement it
[12:22] <mpetyx> ... IBM is also interested in implementing it too
[12:23] <mpetyx> PhilA, what are the advantages of property graphs comparing to similar implementations?
[12:23] <mpetyx> Andy, explains some differences between the graphs.
[12:24] <mpetyx> ... different use cases require this group.
[12:25] <mpetyx> ... six month is not a time frame for such an implementation
[12:25] <mpetyx> PhilA, how the property graphs fit in with the overall architecture of the web?
[12:26] <mpetyx> Ashok, they use uris and the API will use http and REST.
[12:27] <mpetyx> PhilA, what is the motivation for changing and the difference from Semantic Web?
[12:28] <mpetyx> gkellogg, json-ld is quite interesting on that direction.
[12:28] <mpetyx> ... also interesting for representing graphs
[12:30] <mpetyx> ... we should alienate rdf from property graphs
[12:32] <mpetyx> PhilA, it could be better to work on the api rather than the rdf because not all people like it .
[12:33] <mpetyx> Ashok, if you have some of your data in rdf and some in property graph. then how you integrate that data?
[12:34] <mpetyx> PhilA, different use cases and not using rdf from everything is logical.
[12:34] <mpetyx> ... how much time we have to offer?
[12:34] <mpetyx> ... big names use that technology
[12:36] <mpetyx> ... indeed this idea of pg has a lot of support
[12:36] <mpetyx> Ashok, new members from small companies?
[12:37] <mpetyx> PhilA, that would be good
[12:38] <mpetyx> ... there are some issues with the companies not been already part of the W3C
[12:39] <mpetyx> ... do you think your organisation could join?
[12:41] <mpetyx> ... implementation reports by spring 2015
[12:42] <mpetyx> ... Ashok will be the chair.
[12:42] <mpetyx> ... Kelvin and IBM are also going to join
[12:43] <mpetyx> Ashok, if w3c says no we should think about where else we could take this work.
[12:43] <mpetyx> PhilA, how much start time would you need?
[12:44] <mpetyx> Ashok, very small staff involvement.
[12:45] <AndyS> AndyS: Encoding PG in RDF gets into issues of appropriateness for the use cases and whether (RDF) tools are appropriate.
[12:46] <mpetyx> PhilA, not much time by W3C staff -- 0.1
[12:46] <mpetyx> Ashok, should we start?
[12:47] <mpetyx> PhilA, i cannot decide so i will talk with the rest and let you know. there is a strong case here
[12:47] <mpetyx> ... it will take almost a week
[12:49] <zwu2> it also depends on how long the process is :)

[12:51] <mpetyx> PhilA, the WG could lay the ground for future work on query language
[12:52] <mpetyx> ... if the group is successful there is going to be a follow up
[12:53] <mpetyx> Topic: anything else?
[12:53] <mpetyx> end of the meeting
