What is the Geo-Metadata Network Suite?
The Geo-Metadata Network Suite is a realization of the vision about geo-metadata (c.f. here).
The Geo-Metadata Network Suite consists of the following components (web applications and open surce projects):
- Geometa.info, the meta-searchengine for the discovery of geospatial data and services (web applications, e.g. with different reader interfaces)
- Geometa-Directory, a collection of catalogs for browsing in registered geo-metadata; (web application and Open Source project, e.g. with different reader interfaces)
- Geometa-Editor, the database editor for the mangement of own geo-metadata; a catalogue service (web application and Open Source project, e.g. with different reader and writer interfaces)
- Geometa-Tools, tools for the integration, conversion (readers/writers) and validation of geo-metadata (web application)
- DClite4G, information model (proposal) for the exchange of geo-metadata comatible to CSW/ebRIM (Open Geospatial Consortium), Dublin Core and e.g. Google.
Frequently Asked Questions (FAQ)
- What is geometa.info as compared to INSPIRE Geo-Portal and other GSDI initiatives?
- geometa.info os a search engine prototype with a web crawler whereas the above mentioned portals are rather directories or registries, i.e. database catalogs in the sense of OGC's CSW.
- What is the difference of searchengine, catalog, registry and directory?
- searchengines contain also 'non-registered' geospatial resources as compared to catalogs; they often only have partial (metadata) information but list ranking search results. Registry and directory aren't defined that consisely. Both consist of collections of registered catalogs and/or geospatial resources.
