Expert Nominee Qualifications:

Candidate for this expert team should have the following qualifications:

Experienced with the Java2 platform (mandatory requirement).
Experience with issues in implementing Object and Relational Databases.
Familiarity with ODBC and JDBC database connection technology.
Familiarity with Object-Relational mapping tools and issues.

Section 2: Request

2.1 Please describe the proposed Specification:

The charter for the Data Services Expert team is to define an abstraction for database services. The data server provides a three-tier architecture, which allows database independence across relational and object oriented databases. It also provides the publication of databases as services in an object-oriented manner. This technology includes techniques to make relational databases look object oriented, such as Object Relational mapping of database tables to objects. This technology will allow large databases to be easily distributed.

The Data Services Expert team will be responsible for developing the following:

Data Services specification
Data Services Reference Implementation
Data Services Compatibility Test Suite.

2.2 What is the target Java platform? (i.e., desktop, server, personal, embedded, card, etc.)

This specification is target towards the J2SE and J2EE platforms. It is anticipated that a J2ME platform will be able to use these services, but not necessarily host them.

2.3 What need of the Openwings community will be addressed by the proposed specification?

The need to access database services is covered by this specification.

2.4 Why isn't this need met by existing specifications?

No.

2.5 Please give a short description of the underlying technology or technologies:

This specification will utilize the following technologies: Java Database Connectivity (JDBC), Object Relational Mapping Tools, Relational Databases, and Object Databases.

2.6 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)

The proposed package for this specification is net.openwings.data.

2.7 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?

No.

2.8 Are there any security issues that cannot be addressed by the current Openwings security model?

No.

2.9 Are there any internationalization or localization issues?

This OSR is targeted towards systems that may be internationally deployed and hence use the internationalization features of Java. It is anticipated that the existing internationalization infrastructure will be sufficient for this OSR.

2.10 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?

2.11 Please describe the anticipated schedule for the development of this specification.

Currently a draft specification exists as a contribution and starting point. The following schedule applies:

Milestone	Date
Openwings Specification Request Approved	12/1/2000
Form Expert Group	3/16/2001
Participant Draft	TBD
Participant Review	TBD – 2Q 2001
Public Review	TBD – 2Q 2001
Beta Release	TBD – 3Q 2001
Maintenance	TBD

Once the expert team is formed the finalized schedule will be made available.

Section 3: Contributions

3.1 Please list any existing documents, specifications, or implementations that describe the technology.

The Motorola/Sun Openwings team, has previously generated work that is being contributed as a basis for this OSR. In particular the following contributions available at http://www.openwings.org/download.cfm#specs are relevant.

Openwings White Paper
Openwings Naming Specification (Alpha version 0.7)
Openwings Architecture Specification (Alpha version 0.7)
Openwings Interface Specification (Alpha version 0.7)
Openwings Component Services Specification (Alpha version 0.7)
Openwings Connector Services Specification (Alpha version 0.7)
Openwings Management Specification (Alpha version 0.7)
Openwings Policy Specification (Alpha version 0.7)
Openwings Data Services Specification (Alpha version 0.7)

In addition to the specifications an Alpha implementation of the existing data service specification is being provided for this effort.

3.2 Explanation of how these items might be used as a starting point for the work.

The existing specification and reference implementation serve as a working model of the data services that can be used to further refine the specification.

Section 4: Additional Information (Optional)

4.1 This section contains any additional information that the submitting Member wishes to include in the OSR.

None.
