Metadata

Metadata Metadata provides information about a piece of data. It is used to summarize basic information about data, which can make working with the data easier. In the context of Keyfactor Command, the certificate metadata feature allows you to create custom metadata fields that allow you to tag certificates with tracking information about certificates. in Keyfactor Command allows dynamic information about a certificate, or other data associated with a certificate that isn’t included in the cert itself, to be associated with the certificate within Keyfactor Command. A metadata field can be defined within Keyfactor Command of a given type with a variety of other attributes, such as default values and security constraints. Currently, the supported metadata types are:

• String

• Integer
  Supports whole numbers only.
• Date
• Multiple Choice
• Big Text
  Big Text fields are limited to 4000 characters. String fields support additional indexing, and so may be preferable to Big Text fields for large databases where possible.
• Boolean
  True/False

Every certificate in Keyfactor Command can be assigned a value for each metadata field defined. The Metadata Web API A set of functions to allow creation of applications.
