"""
Document is an abstract class with all methods
related to document management in ERP5. This includes
searchable text, explicit relations, implicit relations,
metadata, versions, languages, etc.
There are currently two types of Document subclasses:
* File for binary file based documents. File
has subclasses such as Image, OOoDocument,
PDFDocument, etc. to implement specific conversion
methods.
* TextDocument for text based documents. TextDocument
has subclasses such as Wiki to implement specific
methods.
Document classes which implement conversion should use
the ConversionCacheMixin class so that converted values are
stored.
XXX IDEA - ISSUE: generic API for conversion.
converted_document = document.convert(...)
Instances can be created directly, or via portal_contributions tool
which manages document ingestion process whereby a file can be uploaded
by http or sent in by email or dropped in by webdav or in some other
way as yet unknown. The ingestion process has the following steps:
(1) portal type detection
(2) object creation and upload of data
(3) metadata discovery (optionally with conversion of data to another format)
(4) other possible actions
This class handles (3) and calls a ZMI script to do (4).
Metadata can be drawn from various sources:
input - data supplied with http request or set on the object during (2) (e.g.
discovered from email text)
file_name - data which might be encoded in file name
user_login- information about user who is contributing the file
content - data which might be derived from document content
If a certain property is defined in more than one source, it is set according to
preference order returned by a script
Document_getPreferredDocumentMetadataDiscoveryOrderList (or type-based version).
Methods for discovering metadata are:
getPropertyDictFromInput
getPropertyDictFromFileName
getPropertyDictFromUserLogin
getPropertyDictFromContent
The Document class behaviour can be extended / customized through scripts
(which are type-based so can be adjusted per portal type).
* Document_getFilenameParsingRegexp - returns a regular expression for extracting
properties encoded in file name
* Document_getReferenceLookupRegexp - returns a regular expression for finding
references to documents within document text content
* Document_getPropertyListFromUser - finds a user (by user_login or from session)
and returns properties which should be set on the document
* Document_getPropertyListFromContent - analyzes document content and returns
properties which should be set on the document
* Document_findImplicitSuccessor - finds appropriate version of a document
based on coordinates (which can be incomplete, depending if a document reference
found in text content contained version and/or language)
* Document_findImplicitPredecessorList - finds document predecessors based on
the document coordinates (can use only complete coordinates, or also partial)
* Document_getPreferredDocumentMetadataDiscoveryOrderList - returns an order
in which metadata should be set/overwritten
* Document_finishIngestion - called by portal_activities after all the ingestion
is completed (and after document has been converted, so text_content
is available if the document has it)
* Document_getNewRevisionNumber - calculates revision number which should be set
on this document. Implementation depends on revision numbering policy which
can be very different. Interaction workflow should call setNewRevision method.
Subcontent: documents may include subcontent (files, images, etc.)
so that publication of rich content can be path independent.
Consistency checking:
Default implementation uses DocumentReferenceConstraint to check if the
reference/language/version triplet is unique. Additional constraints
can be added if necessary.
