Empower Metadata with Fluid Topics

Technical Notes

Built-in metadata come with a predefined metadata key that administrators cannot change. However, administrators can define one or more values for each built-in metadata key.

The characteristics of built-in metadata are as follows:

  • They associate a string value with a key.
  • They begin with ft:, such as ft:title.
  • Fluid Topics generates them automatically based on the information defined in the content.

The table includes all the built-in metadata that Fluid Topics generates for content uploaded to a tenant:

ft:baseId ID used to build links to a cluster within a topic.
ft:clusterId ID used to cluster different versions of a publication in the Search page.

ft:document_type Displays the type of an unstructured document.
ft:editorialType Displays the editorial type of a map (book or article).
ft:filename Name of the file for unstructured documents.
ft:isArticle Is true for documents with ft:editorialType=article, false otherwise.
ft:isAttachment Is true for attachments, false otherwise.
ft:isBook Is true for documents with ft:editorialType=book, false otherwise.

The last edition date is different from the last publication date. For information about how Fluid Topics calculates these values, see Types of Dates in Fluid Topics.

Built-in metadata should have only one value. Multi-valued built-in metadata causes publishing errors.

Built-in metadata is sometimes referred to as semantic metadata.
