06 <Dan_Davis> Chris: Fedora Object model has not been discussed much as part of 4.0 planning.
06 <Dan_Davis> Chris: Set aside versioning and other warts in the current design.
07 <Dan_Davis> Chris: Has come up especially early with Topaz (Ambra)
08 <Dan_Davis> Chris: Consider about modeling as open Rdf (named graph) instead of a current form.
09 <Dan_Davis> Chris: Graph eventually related eventuall to immutable bytestreams
11 <Dan_Davis> Adam: Had a similar discussion with Steve
12 <Dan_Davis> Adam: Runs into object model.
12 <Dan_Davis> Adam: Has constructed an OWL ontology.
14 <Dan_Davis> Chris: Yes there are many facets, Started with storage.
15 <Dan_Davis> Chris: Very open data model but started with lowest level package.
17 <Dan_Davis> Adam: RDF pointing to package.
17 == barmintor ~barmintor@cpe-72-229-190-215.nyc.res.rr.com has joined #duraspace
17 <barmintor> can someone post the code for the conf. line? I don
17 <barmintor> t seem to have a note of it at this machine
17 <ajs6f> RDF taking on the functionality of package
18 <cwilper> Via Phone (US Number): +1(805)399-1200, Access Code: 341861
18 == tdonohue ~tdonohue@c-67-177-108-221.hsd1.il.comcast.net has joined #duraspace
19 <barmintor> thanks cwilper
23 <Dan_Davis> Dan: We should understand that we have a balancing act to do to make useful piece of infrastructure
25 <Dan_Davis> Dan: At Fedora's core it is a bridge between fine-grained and course-grained information systems - but itself is based on the lowest end include course-grained immutable bytestreams.
26 <Dan_Davis> Chris: Much more open ended model - possibly in OWL but graph oriented regardless.
27 <Dan_Davis> Adam: Earlier - Facing object model
29 <Dan_Davis> Adam: Dissemination provides a facade (always dynamic) where you can get the graph or parts.
31 <Dan_Davis> Ben: Do services go away.
32 <Dan_Davis> Adam: Not necessarily but need to be rethought.
35 <barmintor> Well, it depends on what folks we're talking about
37 <Dan_Davis> Chris: Not a quad store, no big quad store in the sky.
37 <Dan_Davis> Adam: yes, even linked data.
38 <Dan_Davis> Adam: Likely internal graph for durability
39 <Dan_Davis> Adam: Web lacks this notion.
41 <ajs6f> Web lacks that value, even.
41 <barmintor> I have a devil's advocate comment re: IDs, and a suggestion about process
41 <Dan_Davis> Chris: There is a PREMIS owl model.
46 <Dan_Davis> Dan: Tension between flexibility, openness and interoperability
47 <Dan_Davis> Eddie: Why have poople not used Fedora maybe we have overconcentrated on openness.
48 <Dan_Davis> Chris: What has Fedora not been taken up or dropped. What features: Scaling.
49 <Dan_Davis> Eddie: Get the "whys'" out in the open.
49 <Dan_Davis> Eddie: We have talked about objects as named graphs.
49 <Dan_Davis> Adam: We want to do richer Rdf and need to use blank nodes.
51 <barmintor> When do blue-sky conversations on the committer call become publicly available design propositions that the community can respond to?
52 <ajs6f> And how?
52 <barmintor> I thnk this is a necessary step in the resolution of some sticky issues
53 <Dan_Davis> Dan: What happen when intellectual object are overlayed on Fedora objects.
53 <Dan_Davis> Eddie: We need to find out what are the real issues.
57 <Dan_Davis> Eddie: What is Fedora's special sauce?
59 <Dan_Davis> Chris: Some of the questions about Quad and named graph is intended to serve other uses.
59 <eddies> gotta run. have another call
03 <Dan_Davis> Dan: Reacting to Bens statement: How do we redesign and not just have words in the air.
05 <Dan_Davis> Ben: How do we engage constituents. Start with forming the use case and publish it. Be willing to reconsider if feedback indicates a new direction.
05 <barmintor> I DEMAND IT!
05 <Dan_Davis> Adam: Agrees.
06 <Dan_Davis> Adam: We have and need experimentation.
07 <Dan_Davis> Ben: Checksum bug.
07 <Dan_Davis> Ben: FCREPO-787
08 <Dan_Davis> Ben: Worked out policy problem, tests - does not work with FESL.
11 == elschlomo 2e05a4bb@gateway/web/freenode/ip.46.5.164.187 has quit 245 seconds
11 <Dan_Davis> Ben: Trying to Springify FESL. So non-web layer policies work.
12 <Dan_Davis> Chris: Significant change, should be considered, notes that enforcement need not be a both layers.
13 <Dan_Davis> Chris: Currently a lot of copy and paste code.
13 <Dan_Davis> Chris: Should the policy enforcement be appropriate to the layer.
14 <Dan_Davis> Adam: Should not be in the web layer anyway, should be lower.
15 <ajs6f> Valedicte
15 <ajs6f> \quit
