I am pleased to announce today public access to the Interactive
Geometric Database.

The web address is http://130.15.26.66 

This address has been registered as grdb.org

The Interactive Geometric Database uses Java servlet technology and a
JDBC module with PostgreSQL as the DBMS for a collection of
manifolds. These are stored only in terms of a metric or set of basis
vectors along with constraints and referencing data. This information
is processed interactively through GRTensorJ, a Java interface to
GRTensorII, which in turn runs on Maple. The program TTH is used to
translate TEX into HTML within the database. The database allows for
public input.

Mustapha Ishak and Kayll Lake have done the initial development of the
database. This has been funded in part by grants to Kayll Lake from
the Natural Sciences and Engineering Research Council of
Canada. Mustapha Ishak was supported in part by OGSS and OGS
scholarships.
