** Peter gave synopsis of the state of affairs, and the need for SOCoP folks to make a SOCoP-OOR presentation/demo in about a week
** Mike: was able to install a v0.2 "NCBO Appliance" VMware image on his notebook (a fairly old Mac); doing the same for v0.3 was mixed, but was able to make most things work (with some exceptions)
*** Ken (will follow Mike's install process and) arrange to have a "NCBO Appliance v0.3" VM run on an NEU hosted machines
**** Ken will drop in the new logo, and customize the IPR License
**** once running, Ken & Tejas will provide Mike with access to the vm
**** Mike / Ken / Tejas / Peter will start a wiki page to capture - [[OOR_SandBox_Customization]] - ... will use the [oor-dev] list too, for email exchange
**** Peter will add the dns record map that instance to socop.oor.net (Ken to provide IP) - it would be either 129.10.112.163 or 129.10.112.167 - Ken will confirm later after checking up on available resources
*** ALL: the aim is to get all the above up and running within 24 to 48 hours, so the SOCoP folks can start doing their "content" work and prepare their presentation

Session Co-chairs: [[User:KennethBaclawski|Ken Baclawski]] & [[ToddSchneider|Todd Schneider]]  
== Proceedings: ==
 
[[ToddSchneider|Todd Schneider]]: Here's where we are at, in terms of consensus arrived at from the
 
previous "OOR Architecture and API" workshops:
 
0) The interface for searching ontology metadata will consist of a single method
 
0.a) The method will have a single parameter consisting of a SPARQL query.   
 
0.b) The return value of the method will be a SPARQL result set.
 
0.c) Metadata will be represented using a named RDF graph.       
 
0.d) Metadata will be based on an extension of OMV.   
 
o The OMV extension may include a notion of domain specification or
 
topics, represented as text. 
 
0.e) Metadata will be federated, so it is a single named RDF graph, no matter
 
how many OOR instances there are. pics, represented as text.

  • Discussion on possible adjustments in the OOR architecture and work plans in view of what transpired from last week's Joint NCBO-OOR Team Meeting - ref. OOR/ConferenceCall_2011_09_13
  • The specifications to be discussed at the these workshops are the following (not necessarily discussed in this order):
    • the OOR Architecture
    • the OOR API
    • the Organizing Plan
    • the default development platform

Abstract

As a result of the two OOR Architecture and API panel sessions back in Oct & Nov-2010, we have been exposed to a large number of architecture and API candidates for ontology repositories. We have had requirements for the OOR, at least in broad outline form, since the Ontology Summit 2008. We have been running an OOR sandbox based on BioPortal. Most recently, we have forked from the BioPortal code base with the intention of proceeding separately with the development of a reference implementation.

At this series of meetings, we are going through the process of producing the actual OOR specification. It will be run as a workshop where the straw man proposal will be discussed and modified as needed.

The various architectures and APIs for ontology repositories presented for consideration are available at OpenOntologyRepository_Architecture

Here is the straw man architecture: OpenOntologyRepository_Architecture/Candidate03

In addition, there is an API of the core services that was obtained from BioPortal, which is not entirely compatible with the straw man architecture, but furnishes a starting point. This API will also be discussed and modified as needed.

Here is the API expressed in WSDL: http://www.ccs.neu.edu/home/kenb/oor/OORService.wsdl

Here is the API expressed in Java: http://www.ccs.neu.edu/home/kenb/oor/OORI.java

Finally, we need to agree on a plan for completing the development of the specification.

Here is the proposed organizing plan: OpenOntologyRepository_Architecture/GettingOrganized

We encourage all participants to update your candidate contributions to ensure your ideas are known and understood.

The following are relevant prior meetings:

Welcome to the OpenOntologyRepository: Architecture & API Workshop-VIII - Tue 2011_10_11

Session co-Chairs: Ken Baclawski & Todd Schneider

see session page at: http://ontolog.cim3.net/cgi-bin/wiki.pl?OOR/ConferenceCall_2011_10_11

Proceedings:

Todd Schneider: Here's where we are at, in terms of consensus arrived at from the

previous "OOR Architecture and API" workshops:

0) The interface for searching ontology metadata will consist of a single method

0.a) The method will have a single parameter consisting of a SPARQL query.

0.b) The return value of the method will be a SPARQL result set.

0.c) Metadata will be represented using a named RDF graph.

0.d) Metadata will be based on an extension of OMV.

o The OMV extension may include a notion of domain specification or

topics, represented as text.

0.e) Metadata will be federated, so it is a single named RDF graph, no matter

how many OOR instances there are. pics, represented as text.

0.f) Metadata will be federated, so it is a single named RDF graph, no matter

how many OOR instances there are.

1) Each OOR instance must declare the representation language module it supports.

2) Every OOR shall support RDFS

3) Quality and Gatekeeping. We distinguish between gatekeeping and quality control.

Definition: Gatekeeping specifies the a set of minimal requirements that any

ontology within the OOR has to meet. The latter are intended to

enable the users of the OOR to find quickly ontologies that fit

their needs; the criteria do not ensure the quality of the ontologies.

3.a) Gatekeeping will vet the metadata associated with an ontology to ensure

entrance criteria are met.

3.b) For each metadata attribute, it will be specified whether it is required

or optional.

3.b.i) It MUST be specified whether the ontology is available (or to be

available in the future).

3.b.ii) The ontology language MUST be specified.

3.b.iii) Other attributes will be handled offline by Michael Gruninger

based on the OMV specification.

3.c) An ontology must satisfy other requirements depending on the ontology

language.

3.d) Syntax checking is always required and the responsibility of the language

module

3.e) Consistency checking is required with some time limit.

3.f) Gatekeeping criteria will include an attribute to indicate whether the

ontology exists or the metadata represents an advertisement.

3.g) The location of the actual ontology is the responsibility of Administration.

3.h) Metadata needs to include an attribute for the 'availability' of the ontology

3.i) 'Location' of the ontology must be provided.

3.j) The representation language of the ontology is a required attribute.

3.k) Michael will provide a preliminary list of required metadata attributes.

3.l) Submission process will be asynchronous

Peter P. Yim: moving us forward ...

Peter P. Yim: now that we have the partitioning (architecturally), we need to adopt a

development platform (say, something like "eclipse"), and start having

team members claim ownership to developing specific modules

Ken Baclawski: Look at http://www.eclipse.org/stp/

Todd Schneider: http://ontolog.cim3.net/cgi-bin/wiki.pl?OpenOntologyRepository_Architecture/Candidate03

Peter P. Yim: also (important), please refer to the BioPortal "tab" implementation details

- see: http://palexander.posterous.com/extending-bioportals-rails-ui

Todd Schneider: The 'administration' module is responsible for advertising which

representation languages an instance supports.

Peter P. Yim: All: we might want to partition some of the work to sizes that fit,

say, work by a student in 3-months (which might mean work that takes

an experienced developer a couple of weekends or a month to do)

Todd Schneider: The next Architecture meeting will focus on development platform and work partitioning

Todd Schneider: The next meeting will be on Tue 1 November 2011, same time

Todd Schneider: Homework: learn more about the Eclipse and its capabilities;

Read Paul Alexander's page on tabs

- http://palexander.posterous.com/extending-bioportals-rails-ui

Peter P. Yim: we'll make that (choice of platform and work partitioning) as the main focus of

our next team meeting (Tue 2011.11.01)

Todd Schneider: We need to motivate contributors to provide 'comic' book level descriptions

of their work

Peter P. Yim: -- session ended 9:38am --
