USGIN joins CS IDEC in developing the CatalogConnector CSW client

USGIN has joined Infrastructura de Dades Expaciales de Catalunya (IDEC) in developing the opensource CSW client CatalogConnector.

(09/28/2009, http://www.geoportal-idec.net/geoportal/cas/noticies.jsp)

To expand on the article, USGIN is contributing to the CatalogConnector in hopes of making the software more user friendly and efficient. As such, USGIN has already contributed code to improve front end user capabilities and optimizations to improve http response speed. If you have any requests or suggestions in regard to the CatalogConnector, please drop us a line.


"GeoNetwork opensource is a catalog application to manage spatially referenced resources. It provides powerful metadata editing and search functions as well as an embedded interactive web map viewer"

"GeoNetwork opensource has been developed to connect spatial information communities and their data using a modern architecture, which is at the same time powerful and low cost, based on the principles of Free and Open Source Software (FOSS) and International and Open Standards for services and protocols (a.o. from ISO/TC211 and OGC)"

USGIN's primary interest in this client/server hybrid application package is its CSW service and ISO 19139 metadata capability. GeoNetwork also include the Geoserver (WMS, WFS, WCS servers) and Intermap (WMS client) Web applications.


CatalogConnector is an open source, Java based CSW client that can search multiple CSW catalogs and CSW implementation versions at once.

OGC CSW APISO - OGC ISO19115/ISO19119 application profile for CSW 2.0


This document specifies a profile of the OGC Catalog Service for the Web (CSW) 2.0.2 using the ISO 19115/ISO19119 metadata content model,  with support for XML encoding per ISO19139 and HTTP protocol binding. The profile relies on requirements coming from the CS/CSW 2.0.2 specification (OGC CSW 2.0.2, OGC document 07-006).


OGC Catalog service for the web (CSW 2.0.2)


The OpenGIS® Catalogue Services Interface Standard (CAT) supports the ability to publish and search collections of descriptive information (metadata) about geospatial data, services and related resources. Providers of resources use catalogues to register metadata that conform to the provider's choice of an information model; such models include descriptions of spatial references and thematic information. Client applications can then search for geospatial data and services in very efficient ways.

A useful basic description of CSW function can be found at this OGC Tutorial.



deegree is a Java Framework offering the main building blocks for Spatial Data Infrastructures. Its entire architecture is developed using standards of the Open Geospatial Consortium (OGC) and ISO/TC 211 (ISO Technical Committee 211 -- Geographic Information/Geomatics).

USGIN CSW Profile Home

A web service interface to search metadata catalogs. With the funding of the GIN project, and its dependency on existing (GEON, NGMDB) or soon to exist (NGGDPP) hosts for catalog/discovery services, the specification for how catalog services will work is a high priority for community convergence. There are many benifits to the community offered by a standardized approach to registering and discovering geoscience information resources.

Discussion at the GIN kickoff workshop in Houston, and at a subsequent meeting with Steve Richard, Ashraf Memon and Kai Lin at SDSC, indicated that the Open Geospatial Consortium (OGC) Catalog Services for the Web (CSW) specification (07-006r1 Catalogue Services Specification v.2.0.2 ) offered an existing specification for catalog services that could meet requirements of all the interested parties.

CSW Debug Blog

A group blog to discuss metadata Catalog Service for the Web (CSW) implementation experiences

Post to this group blog about your metadata Catalog Service for the Web (CSW) client and server implementation efforts and debugging sagas. I encourage occasional rants of the cathartic nature.
