# Labels

Labels are a convenient mechanism for adding semantics to PageSeeder artifacts. They are divided in two broad categories:

- [object labels](/reference/glossary/object_labels.md) – apply to PageSeeder objects such as [documents](/reference/glossary/document.md), [fragments](/reference/glossary/fragment.md), etc.
- [content labels](/reference/glossary/content_labels.md) – apply to text content inside PageSeeder documents.

The following table summarizes the different types of labels used in PageSeeder:

| Type | Label | Applies to |
| --- | --- | --- |
| Content   | [Inline label](/reference/glossary/inline_label.md) | Inline content inside a block of text (equivalent to a `<SPAN>` in HTML) |
| [Block label](/reference/glossary/block_label.md) | Blocks of text (equivalent to a `<DIV>` in HTML) |
| Object   | [Document label](/reference/glossary/document_label.md) | A PageSeeder document |
| [Fragment label](/reference/glossary/fragment_label.md) | A document fragment |
| Comment label | A [comment](/reference/glossary/comment.md) or [task](/reference/glossary/task.md) or [workflow](/reference/glossary/workflow.md) |
| Upload label | A document on upload |
| Creation label | A document when it is created |
| Version label | A specific [version](/reference/glossary/version.md) of a document |
| [Edit note label](/reference/glossary/edit_note_label.md) | A note on a document edit |
| [Cross-reference (xref) label](/reference/glossary/cross_reference_label.md) | A [cross-reference](/reference/glossary/cross_reference.md) |

Label names can contain the following characters:  
`[a-z][A-Z][0-9][-_]`

For further information regarding allowable values for PageSeeder objects, *see* [datatypes](/psml/datatypes/pageseeder_datatypes.md) and [label config](/reference/folders_and_files/project_template/label.md).
