Compressed Markup Language

Compressed Markup Language (CML) is a compact binary form of HTML content used in the web clipping applications in Palm OS. The HTML code is converted to a sequence of bytes of a tokenized format.

On the Palm devices, the CML code is then combined with other Web content such as images. The bytes of the binary representation are further compressed in a bitwise scheme where fewer than 8 bits are used to encode many common characters. The result is what is known as PQA format (for Palm Query Applications), which is placed into a database format similar to PDB and PRC. CML is apparently not stored separately other than as part of the PQA format.
