Metadata

Metadata is usually described as being ‘data about data’. There are a number of reasons why an organisation may want or need to manage metadata:

A trend towards centralised data requires metadata to allow users of the data to locate and understand what the data is and how it should be used.
Increasingly, data suppliers need to provide metadata as a companion to accurately describe the data, it’s source and it’s proposed use.
Anyone who needs to share data can benefit from maintaining and supplying metadata to ensure that the data is used in context and that the recipient understands the data.
Legislation, such as Inspire, requires certain data custodians to provide data and metadata for national and European initiatives.

Cadcorp has implemented support for Metadata using a centralised storage area in GeognoSIS and provides a desktop integration with SIS to allow the user to create, view, edit, import and export metadata. Additionally, users can harvest metadata from database sources, import Gemini 2.2 files, search the metadata repository and manage metadata records. The metadata repository can also be searched using a browser, utilising OpenSearch.

The metadata repository created and stored within GeognoSIS is accessible through the Open Geospatial Consortium Catalog Server (Web) interface. This is usually abbreviated to OGC CS-W. More information about this can be found at http://www.opengeospatial.org/standards/specifications/catalog. This is recognised as the preferred interface for an open and accessible metadata repository, providing a published query and update interface which is accessible through the web.

GeognoSIS currently supports the ebRIM and Dublin Core profiles of the OGC CS-W.
