5  Open Discussion

The open discussion session is used to give members of the Grid community the ability to voice their opinion about activities or planed activities that should be hosted within this working group. We like to here from you in advance in order to give you the chance of a small presentation of an activity you like to do or you like to see. Presentations should be limited to 10 minutes.

During this discussion we hope also to determine future activities.

One of the goals we have it to clearly identify implementation teams and stakeholders for the development and deployment of the suggestion the Grid Forum is performing.

6  Jini Task Group

Mailing lists

We would like that you send a mail to in case you or your colleages are interested in this activity, but are not listed above.

We also like to here if any of your projects already include Jini so we can establish a catalogue of Grid-Jini related activities.

6.3  Activity

This document outlines initial ideas at the EuroPar meeting (August 2000). The objectives of this document are to act as an initiator of discussion, and identify possible interest in the use of Jini within the Grid infrastructure.

1. Write an initial statement what this working group is supposed to be doing

2. Identify more possible collaborators for the working group

3. Use the gis-wg for communication

a. Use [JINI] as topic indicator

b. Should this be announced at Grid Forum (?)

We envision that the first task of this group will be to define a charter, which will involve the following aspects

We propose to create a working group to initiate discussion on the use of Jini within the Grid infrastructure. Propose as part of the Grid Forum to initiate a JINI investigation group. The first task of this working group will be to define a charter stating objectives, aims, and key participants within the community, to investigate the aspects defined below. Participants will also be encouraged to provide prototype implementations.

1. The group will be established jointly between the Grid Forum and the JavaGrande consortium

2. Investigate ways in which Jini can be used as infrastructure within Grid, and to identifies deficiencies in Jini that may need to be overcome

3. Investigate Jini services such as

- Leasing,

- Transactions,

- Inter-domain security and access control lists

- Fuzzy pattern matching,

- Service discovery

- Resource management

4. Scalability of Jini infrastructure and performance to support Grid enabled applications

5. Participants will be encouraged to work jointly on prototype implementations, based on consensus within the group

6. Provide resources and seminars on Jini for members of the working group.
Is a seminar series necessary to educate members on Jini? Should a web page on Jini resources be developed?

7. Issues in deployment and use of Jini

8. Identify current work within the Jini community, and overlaps between requirements

and impacts of this working group

6.4  Proposed Activities at the Grid Forum in Boston

Though no commitment from SUN has been officially made, we expect a tutorial and a participant from the Jini group to participate on a BoF session.

7  Relational Database Task Group

As suggested in a previous Information Service Group meeting a new Task group is being defined. This task group will be presented at the next Grid Forum and a first result will be presented during the meeting.

7.1  Title

Relational Data Models for Grid Information

7.2  Contact

Peter A. Dinda, Northwestern University ()
Beth Plale, Georgia Tech ()

7.3  Abstract

This task group will study the feasibility, practicality, benefits, and drawbacks of using a relational data model (eg, SQL) for Grid information as an adjunct of or an alternative to the current hierarchical data model (eg, LDAP) . The group will produce a report describing the results of the study, as well as a recommendation as to whether a standardized relational data model should be pursued.

A relational data model has several potential benefits:
- enabling complex queries spanning and aggregrating many resources
- leveraging sophisticated, scalable database technology
- providing inherent extensibility of grid information types
- creating interesting new database research problems

This task group will determine if these and other benefits outweigh the increased complexity of the relational model.

7.4  Presentations

The currently forming Relational Data Models for Grid Information task group (see below) will present the following talk at the next Grid Forum Meeting

The LDAP Query Language: Limitations and Opportunities

Presented by Beth Pale

Abstract:

LDAP is based on a hierarchical data model, thus suffers limitations in its query language that are endemic to the data model. In this talk, I use grid information service example queries to highlight the limitations of the query language, then discuss opportunities in the form of current research that addresses these limitations.

Note: This group also suggest a second talk if time permits.
