Fragment

Documents in PageSeeder are composed of fragments.

Fragments can have a comment thread attached to them. If the document can be edited or is in an editable format such as PSML, its fragments can also be edited.

Fragments have unique identifiers (IDs) that are either generated by the system or can be assigned through markup.

Where fragment IDs are created through markup, fragments can be edited programmatically. This can be very useful where there is a need to update only specific parts of a document.

Fragments are grouped into sections.

All documents have a default fragment, which is used to refer to the entire document.

PSML

In PSML, fragments are usually represented using the <fragment> element. 

There are also specialized fragments:

• <properties-fragment> – for properties (simple data-value pairs).
• <xref-fragment> – for lists of cross-references.
• <media-fragment> – for non-PSML content.

Fragments can be added, removed, or repositioned within the section or document, if in the document template:

• The document structure isn’t set to locked.
• The document or sections aren’t set to be read only.
