[12:06] <Michael_Petychakis> it's ok!
[12:06] <Ashok> Minutes approved without objection
[12:11] <Ashok> Ashok:TOPIC: How do we make the case that Property Graphs are useful in commercial situation
[12:12] <Michael_Petychakis> by developing more use cases focused on commercial applications?
[12:13] <Ashok> zhe:Usecase from a user ... break up property graphs into clusters and then act on clusters
[12:14] <Ashok> ... predict behaviour basede on your friends' behaviour
[12:15] <Ashok> Ashok:Please write up and send to mailing list
[12:15] <Ashok> Andy:Where does the data come from?
[12:15] <Michael_Petychakis> ok, the breaking up seems like a procedure of a resolver or of an engine. not like the core feature of property graphs. prediction is indeed interesting as a core characteristic
[12:16] <Ashok> zhe:raw data is a call log
[12:18] <Ashok> zhe:personalized page ranking
[12:18] <Ashok> ... find most important players
[12:19] <Ashok> Michael, can you send mail re. your question?
[12:19] <Ashok> zhe:important people have higher PR value
[12:19] <Michael_Petychakis> yes yes. after the call finishes, i will send it on the mailing list.
[12:20] <AndyS> graph-per-app (base data -> graph -> application) or graph reused by several applications (and evolving applications)
[12:22] <Ashok> Ashok:We heard that Twitter and LinkedIn use property graphs ... can we get details?
[12:24] <Ashok> Andy:What is exposed externally and internal representation may be different
[12:27] <Ashok> ... can we get examples of internal uses of PGs

[12:30] <Ashok> Great!I will take a look
[12:31] <Ashok> Kelvin:Discusses usecases inside the enterprise
[12:35] <Ashok> Ivan:Social sites do not tell us what they are doing
[12:36] <Ashok> ... perhaps scientific uses
[12:36] <Ashok> ... perhaps in the medical world, astrophysics, astronomy ...
[12:38] <Ashok> ... we should find uses other uses other than social sites ... they may be more open to standards
[12:40] <Ashok> Kelvin:I was hoping more folks would join the CG and that would help with getting usecases
[12:43] <Ashok> TOPIC:Extending RDF to accommodate PGs
[12:44] <Ashok> Ivan:Some folks bitten by anti-RDF bug
[12:44] <Ashok> ... so if we talk about extending RDF they may say W3C is again pushing RDF again
