Minutes

1. Review of EMS 1.0 REST API

DaveJohnson is currently editing the OSLC Core specification that all workgroups should adopt. The current EMS 1.0 REST API specification contains some material that should be replaced with references to the OSLC Core specification when that is finalized.

Architecture

ArthurRyman reviewed the Architecture page. The main issue that requires further discussion is how multiple servers should collaboration. The current specification makes the simplifying assumption that all resources for a given project are stored in one server. This allows searching and baselining to be performed easily. In practice, there may be several servers, e.g. there may be one for PPM and one for estimation, or there may be two for estimation. The specification should clearly state where the assumption of a single server is used, and possibly relax this constraint or describe how multiple servers should work together. In some cases this may cause additional work on the part of the consumer.

ACTION: ArthurRyman will add a section on multiple servers to the Architecture page and add appropriate clarifications throughout the specification.

LawrencePutnamJr said that this type of review is better performed for QSM by AndrewCanham, who will participate in the reviews going forward. AndyBerner offerred to help AndrewCanham get up to speed on the spec.

ACTION: LawrencePutnamJr will ask AndrewCanham to review the specification.

Design

ArthurRyman reviewed the Design page. This page describes the general resource design, general usage of HTTP methods, and aspects not covered by this specification. No issues here. We expect further discussion on the applicability of some HTTP methods in some cases.

Data Model

ArthurRyman reviewed the main Data Model page. This page describes some standard properties which should be described in the OSLC Core specification.

2. OSLC Simple Query Specification

ArthurRyman has been editing the OSLC Simple Query specification which the EMS 1.0 specification depends on. It will be incorporated into the OSLC Core specification.

3. Implementation Status

ArthurRyman reported that a Rational product development team has taken over the EMS 1.0 prototype and will continue its development in order to provide implementation experience feedback to the workgroup.
