This page describes recommended metadata best practices and provides a high-level summary of metadata requirements for data objects when publishing data to the BC Data Catalogue. To learn more about The Core Administrative and Descriptive Metadata Standards and Guidelines, please visit Learn more about the metadata standard.

Metadata is data (or information) which describes some aspect of data. Everything from database table descriptions, data relationship mapping, storing who created/updated data, purpose of the data, can be classified as metadata.
In the DataBC Program, we value the importance of using metadata to describe the data we serve and we strongly encourage activities that support and create valuable metadata documentation.
- Provides business context and helps bring an understanding to the data
- Facilitates data re-use and sharing
- Defines data structure (i.e.: data flow, data relationships, data dependencies)
- Enables historical data tracking (i.e.: audit columns)
- Facilitates data design discussions
- Provides data consistency
- Supports user self-service to understand the purpose and characteristics of a data set
- Can be used to help troubleshoot data issues; i.e.
- who is the data custodian / person responsible for the data?
- what is the security classification?
- will the change impact other data?
There are international standards for metadata that DataBC follows. This provides interoperability with other data service utilities, meaning that descriptions of your data can be widely published and accessed (assuming your security profile allows this).
- Easy to access and understand for consumers within and outside the organization.
- Produced throughout the application development life cycle.
- Of high quality, and managed effectively.
- Open to improvement, and have a feedback mechanism by which consumers can inform the custodian of incorrect or out of date metadata.
Metadata fields that are mandatory in the catalogue are identied
- From the User Interface (UI)
- From the API
Table and column descriptions are required for all objects in the BC Geographic Warehouse. These descriptions are created by the BCGW data modeller, in consultation with the custodian and DataBC data administration staff. The medium for defining the descriptions is the Dataset Model.
Spreadsheets (Excel or CSV files) uploaded to the BC Data Catalogue must be documented sufficiently so that people looking at the spreadsheet can understand what the columns mean. A good way of providing this information is to supply a data dictionary resource, explaining the purpose and content of the other resources. See for example, a data dictionary for the BC Data Catalogue Content.
