Project Objectives

Our project had a number of specific objectives as well as a general objective of creating a spatial data Validation framework and integrating it with a Web Feature Server. Because we were working with the GeoServer Web Feature Server, we wanted to ensure that GeoServer had the capabilities to be widely useful to CGDI members. We also wanted to ensure that all our products conformed to the standards chosen by CGDI.

General project objective: To create and bundle a Validating Web Feature Server (VWFS) based on the Java language and executable within a J2EE infrastructure.

Specific project objectives:

• to be fully compliant with the OpenGIS WFS specification;
• to inter-operate with existing commercial and open-source spatial databases;
  • to read and write data from OracleSpatial
  • to read and write data from ESRI ArcSDE
  • to read and write data from PostGIS/PostgreSQL
• to include a user interface GeoServer, to make it easier for ordinary users to administer a Web Feature Server;
• to support WFS update validation based on attribute and spatial restrictions;
• to support WFS update validation based on plugable validation modules; and
• to be written in platform independent Java for a J2EE environment
