This document describes how to add support for extended webdav features (locking, properties etc.) to your webdav-aware application. Author: Hamish Rodda, rodda@kde.org Version: 0.3 Compatable with (tested on): Apache + mod_dav version 1 and 2 Zope Silverstream webdav server Applications supporting extended webdav features (include name and contact email, in case the interface has to change): [none currently] Much of the info here is elaborated by rfc #2518; the rest can be understood by reading davPropStat() in http.cpp, specifically the setMetaData() calls. Extended information is transferred via tdeio's metadata system... === MISCELLANEOUS === Display Names (names suitable for presentation to the user) are passed as the metadata element davDisplayName. Source template locations (href, usually an absolute URL w/o host info) are passed as element davSource. Content languages are passed as element davContentLanguage. Extra webdav headers are passed as metadata element davHeader For doing a webdav SEARCH, use listDir() and set the metadata element davSearchQuery to the search query. The root element of this query should be like or . For doing a generic webdav action, call a special request, with the following data: int, value 7 (WEBDAV generic) KURL url int method - the HTTP/WEBDAV method to call Send the xml request and receive the xml response in the usual way. === CREATING A LOCK === To create a lock, call a special request, with the following data: int, value 5 (LOCK request) KURL url - the location of the resource to lock TQString scope - the scope of the lock, currently "exclusive" or "shared" TQString type - the type of the lock, currently only "write" TQString owner (optional) - owner contact details (url) Additionally, the lock timeout requested from the server may be altered from the default of Infinity by setting the metadata "davTimeout" to the number of seconds, or 0 for infinity. === REMOVING A LOCK === To remove a lock, call a special request, with the following data: int, value 5 (LOCK request) KURL url - the location of the resource to unlock metadata required: davLockToken - the lock token to remove and, of course, any other lock information as below required for the operation to suceed. === SETTING LOCK INFORMATION === To provide lock data so that urls can be accessed, you need to pass the following metadata: davLockCount: (uint) the number of locks you are providing davLockToken%1: (string) the token (optional) davLockURL%1: (string) the absolute URL specified by the lock token (optional) davLockNot%1: (value ignored) the presence of this meta key negates the lock (ie. requires the lock to not be set) Example data: ============= davLockCount: 2 davLockToken1: opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76A davLockNot1: (value ignored) davLockToken2: opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76B davLockURL2: http://www.foo.bar/container2/ === RECEIVING LOCK INFORMATION === For each file, stat/listdir always returns two pieces of information: davSupportedLockCount: (uint) the number of lock types discovered for this resource. davLockCount: (uint) the number of locks discovered on this resource. for each count, additional information is returned: =================== Information about the locks on a resource: davLockCount: %1 (the number of locks to be described, as below) *** Required items *** davLockScope%1 - The scope of this lock. May be exclusive, shared, or a custom type. davLockType%1 - The type of the lock. davLockDepth%1 - The depth to which this lock applies (0=only this resource, 1=this collection, infinity=applies recursively) *** Optional items *** davLockOwner%1 - The owner of this lock. davLockTimeout%1 - The timeout parameter. Possibilities: see section 9.8, rfc #2518 davLockToken%1 - The token which iden =================== Information about the lock types supported by the resource davSupportedLockCount: %1 (the number of locks types to be described, as below) davSupportedLockScope%1 - The scope of the lock (exclusive, shared, other custom type) davSupportedLockType%1 - The type of the lock (webdav 1.0 supports only the "write" type) =================== Example Metadata which would be supplied if the response was the example XML below: davSupportedLockCount: 2 davLockCount: 2 davLockScope1: exclusive davLockType1: write davLockDepth1: 0 davLockOwner1: Jane Smith davLockTimeout1: infinite davLockToken1: opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76A davLockScope2: shared davLockType2: write davLockDepth2: 1 davLockOwner2: John Doe davLockToken2: opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76B davSupportedLockScope1: exclusive davSupportedLockType1: write davSupportedLockScope2: shared davSupportedLockType2: write (example XML:) http://www.foo.bar/container/ 0 Jane Smith Infinite opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76A 1 John Doe opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76B HTTP/1.1 200 OK
