The XML Bookmark Exchange Language, or XBEL, is an interchange format for the hierarchical bookmark data used by current Internet browsers. It is defined as an application of the Extensible Markup Language, or XML [BPSM98].
This section descibes the origin of the effort which created the XML Bookmark Exchange Language (XBEL), identifies the contributors, and provides information on the availability of the public text of the DTD and additional documentation on the applications which support XBEL.
The XML Bookmark Exchange Language is a product of the Python XML Special Interest Group (XML-SIG), sponsored by the Python Software Activity (PSA). The initial intent of the XBEL effort was to create a demonstration of XML facilities available to Python programmers which would also be useful.
The initial idea for XBEL was contributed by Mark Hammond. Mark sent his idea to the Python XML-SIG mailing list. This was closely followed by discussions and additional ideas by many of the list participants. The following people contributed to the design of the DTD and the related software (listed in alphabetical order by last name):
Information on XBEL, including the public text and this document, is available on the PSA Web site at http://www.python.org/topics/xml/xbel/ [Dra]. Please refer to this Web resource for information on new versions, DTD variants, and supporting software.
The public text for XBEL will be made available through a SOCAT catalog at available at: http://www.python.org/topics/xml/dtds/catalog. This catalog may be used by including a DELEGATE entry in a catalog already used by XML processing software. The DELEGATE entry should be:
DELEGATE "+//IDN python.org" "http://www.python.org/topics/xml/dtds/catalog"
The XBEL DTD documented in this report has the Formal Public Identifier:
