Resolutions

Actions

• David will write a proposal for the resolution of OSLCCORE-9 for review and potential vote next meeting
• Nick will write up a scenario describing how to finde the component LDPC - i.e., how to determine the usage of a particular LDPC

·         Jim will create a wiki page describing what information is capture in an OSLC2 ServiceProviderCatalog, and what information is available from an LDPC in order to determine the gap.

• Jim will propose additional LDPC OSLC properties in oder to close the above gap so that the same discovery information is available from either discovery approach

·         Jim will discuss ReSpec ownership and maintenance with Chet.

Chat transcript from room: oslc

[07:05] Martin Pain (IBM): Martin Pain joined

[07:08] Jim Amsden (IBM): turtle source for OSLC2 core namespace is in the open-services.net wiki

[07:08] Jim Amsden (IBM): this was used to generate the HTML and RDF/XML for the OSLC2 specs using XSLT

[07:09] Jim Amsden (IBM): the shapes were hand written in the HTML specs

[07:09] Jim Amsden (IBM): there are multiple versions of the XSLT file, not sure if these have all been merged.

[07:10] Jim Amsden (IBM): the same script may not have been used for all the OSLC2 specs, different domains may have used a different version of the XSLT

[07:10] Jim Amsden (IBM): OSLC3 is in better shape with ReSpec

[07:13] Harish (SoftwareAG): Harish to scribe today

[07:14] Harish (SoftwareAG): Any objections to approval of minutes of last meeting?

[07:14] Harish (SoftwareAG): No objections. Minutes approved.

[07:17] Harish (SoftwareAG): Review of TC documents - many recent changes.

[07:19] Harish (SoftwareAG): Update after checking with Chet - TCs can refer to specs not yet OASIS specs. Possible objections but it is up to the discretion of TCs to manage dependencies.

[07:19] Jim Amsden (IBM): OSLCCORE-20 Service provider should describe domain/scope OSLCCORE-9 Bootstrapping discovery OSLCCORE-25 Define a stable URI for OSLC Shape resources OSLCCORE-23 Should a ServiceProviderCatalog or ServiceProvider resource be an LDPC? OSLCCORE-28 Update ReSpec to support multiple vocabulary files OSLCCORE-26 Linking from Service resource to read-only LDPC Added a clause that the same information should be available through any discovery mechanism, SPC, Link or Prefer headers OSLCCORE-16 Discovery should include text about vocabulary discovery OSLCCORE-1 Ian to add scenario to https://wiki.oasis-open.org/oslc-core/DelegatedUIUseCases OSLCCORE-15 Allow client to request different icon sizes for resource preview OSLCCORE-18 link-guidance.html final editing issues

[07:20] David Honey (IBM): https://issues.oasis-open.org/browse/OSLCCORE-9?jql=project%20%3D%20OSLCCORE

[07:21] David Honey (IBM): https://issues.oasis-open.org/browse/OSLCCORE-20?jql=project%20%3D%20OSLCCORE

[07:30] Harish (SoftwareAG): It is difficult to figure out which query capability to use when several are available - what is the OSLC equivalent for a 'project area'?

[07:35] Harish (SoftwareAG): There are discovery problems when the data is partitioned in some way. UseCase - discovering a service provider using an identifier.

[07:36] Harish (SoftwareAG): with reference to unknown types

[07:46] Nick Crossley (IBM): Proposal: use oslc:details, when requested with content type RDF, to point to the 'project area' or equivalent

[07:47] Nick Crossley (IBM): oslc:details may still return a web page when requested with HTML or no specific content type

[07:47] Martin Pain (IBM): Two use cases: 1. A human user looking for the ServiceProvider (SP) a human-readable name 2. An automated process looking for the SP for a data partition for which it has the URI Case 1 Can be addressed by a selection dialog for SPs on the SP catalog. Case 2 can be addressed by using oslc:details to point to an RDF resource which the SP is describing the services of.

[07:48] Nick Crossley (IBM): The resource referenced by oslc:details MAY be an LDPC. It SHOULD have a dcterms:title. The title of the resource may be used to find a particular service provider

[07:51] Jim Amsden (IBM): David will update the proposal in the issue and we will schedule a vote for the next meeting

[08:03] Nick Crossley (IBM): Discussions of OSLCCore-9, Bootstrapping discovery. Is this a nice to have? Discussions about how this topic is related to, or orthogonal to, a decision as to whether or not ServiceProviderCatalog, ServiceProvider, and Service resources are also LDPCs.

[08:11] Nick Crossley (IBM): Here's the current language in the spec:Chat transcript from room: oslc

[08:11] Nick Crossley (IBM): Configuration Management providers MUST provide a single <a href="" href="http://www.w3.org/TR/ldp/#ldpc%22%3ELinked">http://www.w3.org/TR/ldp/#ldpc">Linked Data Platform Container (LDPC)</a> for all components in that provider.</p> <p>This component container MUST be advertised as an <a href="" href="http://open-services.net/bin/view/Main/OslcCoreSpecification#Creation_Factories%22%3EOSLC">http://open-services.net/bin/view/Main/OslcCoreSpecification#Creation_Factories">OSLC 2.0 Creation Factory</a> in the <a href="" href="http://open-services.net/bin/view/Main/OslcCoreSpecification#Resource_Service%22%3EService">http://open-services.net/bin/view/Main/OslcCoreSpecification#Resource_Service">Service resource</a> for the configuration server.

[08:34] Nick Crossley (IBM): Nick is to write a scenario for discovery of the Configuration Management component LDPC
