[09:07] == ajs6f [89361cde@gateway/web/freenode/ip.137.54.28.222] has joined #duraspace
[09:08] <ajs6f> Chris is pleased about progress on submitted issues.
[09:14] <ajs6f> Frank is now assigned FCREPO-1027 and FCREPO-1023.
[09:15] <ajs6f> Chris has word from Thorny that folks from CDC are interested in helping with some development work in order to advance their own projects.
[09:15] <ajs6f> As well as NEH.
[09:16] <ajs6f> Dan skewers the medical establishment.
[09:17] <ajs6f> These projects concern publications after publisher embargoes are lifting.
[09:17] <ajs6f> Also, these groups are running Fedora in the cloud.
[09:18] <ajs6f> They're operating under a federal mandate to push efforts to the cloud.
[09:19] <ajs6f> Chris: Let's not waste time.
[09:19] <ajs6f> Adam: Anything for 3.6 that warrants discussion?
[09:19] <ajs6f> Dan: What about replacing JRDF?
[09:19] <ajs6f> https://jira.duraspace.org/browse/FCREPO-950
[09:19] <kompewter> [ [#FCREPO-950] Evaluate replacements for JRDF - DuraSpace JIRA ] - https://jira.duraspace.org/browse/FCREPO-950

[09:21] <ajs6f> http://incubator.apache.org/stanbol/
[09:21] <kompewter> [ Apache Stanbol - Welcome to Apache Stanbol (incubating) ] - http://incubator.apache.org/stanbol/
[09:22] <ajs6f> Adam: Stanbol uses Clerezza for storing structural RDF.
[09:23] <ajs6f> Chris: We do need to parse RDF in the core.
[09:23] <ajs6f> http://incubator.apache.org/clerezza/
[09:23] <kompewter> [ Welcome to Apache Clerezza ] - http://incubator.apache.org/clerezza/
[09:23] <ajs6f> http://incubator.apache.org/jena/
[09:23] <kompewter> [ Apache Jena - Welcome to Jena ] - http://incubator.apache.org/jena/
[09:24] <ajs6f> Adam, Chris: Jena is quite large, but may be modularized.
[09:25] <ajs6f> Chris: Seseme RIO is fairly light.
[09:25] <ajs6f> Seseme -> Sesame
[09:27] <ajs6f> Adam: What is the relationship of the RDF graph to the objects? This informs how much we want to invest in RDF infrastructure.
[09:27] == tdonohue [~tdonohue@c-67-177-108-221.hsd1.il.comcast.net] has joined #duraspace
[09:28] <ajs6f> Dan: The graph is central, but the implementation is different question.
[09:28] <barmintor> +1 in-memory linked lists
[09:28] <ajs6f> Adam: The graph is a graph, but that doesn't imply that it has to be in a triplestore.
[09:28] <ajs6f> Chris: We _will_ have to parse and deal with RDF.
[09:29] <ajs6f> Dan: Looking at SemWeb architecture (and Linked Data) they see RDF as sending messages. Not so much about triplestores.
[09:30] <ajs6f> Dan: Fedora fits well with that. The triplestore is not necessarily part of the core.
[09:30] <ajs6f> Dan: What does Fedora (in a large sense) need to ask at different scales?
[09:31] <ajs6f> Dan: Low-level questions: about graphs about _how_ the stuff is stored.
[09:31] <ajs6f> Dan: Not content-driven questions.
[09:32] <ajs6f> Dan: This about what Fedora _requires_, not what a given site might want to do.
[09:33] <ajs6f> Frank: Don't we need to abstract out these questions?
[09:33] <ajs6f> Everyone: Yes, and some of it has already happened (Trippi) and some needs to (High Level Store).
[09:35] <ajs6f> Adam: This all argues for changes in the core patterns of workflow.
[09:35] <ajs6f> Dan: High level storage implies those kins of changes.
[09:36] <ajs6f> Ben: Using modern Web service engines supports asynch patterns.
[09:37] <ajs6f> Ben: Which might be a necessary but not sufficient step.
[09:37] <ajs6f> Frank: We may soon have asynch HTTP which would open up the Web APIs.
[09:38] <ajs6f> Chris: This is lower level-- system-to-system interaction.
[09:38] <ajs6f> Adam: This is about the boundaries between arch styles.
[09:39] <ajs6f> Dan: Hopes that Fedora will be a mediator able to support multiple styles of interaction.
[09:41] <ajs6f> Adam: We needed to use other machinery for that mediating purpose precisely because Fedora doesn't do that so well right now.
[09:42] <ajs6f> Dan: Then there's moving from operation-centrism to data-centrism.
[09:44] <Dan_Davis> Ben: Rejiggering FESL configuration files to Spring configuration files
[09:45] <Dan_Davis> Ben: Needs feedback, want eyeballs on code.
[09:45] <eddies> Ben: calling for feedback on FCREPO-795 branch

[09:46] == ajs6f [89361cde@gateway/web/freenode/ip.137.54.28.222] has quit [Ping timeout: 245 seconds]
[09:47] <Dan_Davis> Chris: Is seeing how it all hangs together.
[09:48] <Dan_Davis> Chris: As opposed to all hanging separately.
[09:50] <Dan_Davis> Chris: Normally user configs go into properties files vs xml (unless there is a UI).
[09:51] <Dan_Davis> Ben: This is a good chance to clean up FESL configuration to make it easier to understand.
[09:55] <Dan_Davis> Eddie: This impl is much improved.  Maybe needs related configurations be not widely separated so its less likely that you have unexpected consequences from a change.
[09:59] <Dan_Davis> Chris: Annotation may need one to parse through Java but having a everything in single XML file.
[10:02] <Dan_Davis> Ben: Maybe move annotations to core PEP code for basic CRUD.
[10:02] <Dan_Davis> Dan: I lost connection so someone needs to take notes.
[10:05] <barmintor> Ben: ActiveMQ has a dependency on an older version of slf4j until 3.6 comes out of snapshot, then we can move up to cxf 2.5 or 2.6
