Proposal of an information model to exchange spatial metadata
Initial version by S.F.Keller. See also OSGeodata.
Idea: Take the smallest possible information model for geo-metadata which describes data. Dublin Core (DC) is the most well known model.
This is the full list of (possibly repeatable) attributes from DC together with its semantic interpretation and/or enumeration list:
- Relation: reference - Reference to other metadata records - especially useful for map service types (WxS) pointing to data service types (= file, database?)
- Type: text or enum - Protocol type, e.g. file, WMS, WFS, etc...
- Identifier: string - Unique id to identify an object in a certain context (URL or URN).
- Title: string - Title
- Coverage.box: - Rectangular box (mandatory) in WGS84
- Coverage.name: String - (optionally) a geographic name
- Description: string - Some free text
- Subject: enum - Classification from ISO 19115 as enum type
- Language: enum - ISO Code
- Format: string - File type or name of originating source system
- Source: string - Lineage information
- Date: date - Publication date or date of last change
- Creator: string - Data owner, else: data capturer
- Publisher: string - Distribution informatione
- Rights: string - License information about the data
- Contributor: string - Leave unused?
- Audience: string - Not used or 'GIS' as a constant
Attributes to discuss further (all are probably enums): Type (protocol), Identifier, Coverage.box and Coverage.name and Subject.
