I must emphasize that “document management” and “editing” are entirely separable operations.
Many document management databases, e.g. for a corporate Intranet do not allow user editing of documents. The documents are read-only, and properly so.
Note that the DT Pro Office Web Server mode allows one to distribute the contents of a database to networked users in such a searchable but read-only mode; users (Mac or PC) can search for and read database content but can make no changes to the database. Such a document management system can be useful to an organization for distribution of policy and procedure documents, forms, etc.
The term “document management” has a number of technical definitions and levels in information science. The DT applications are intended to assist single users to maintain and mine information from collections of documents, with some useful and unique artificial intelligence assistance. Personally, I use DT Pro because it helps me manage and analyze the information content in my databases. I use DT Pro as an interactive research assistant.
The phrase you quoted about future changes in the Index capture of document is a simple statement. Currently, one must invoke the Synchronize command to update indexed content; in the future, updates will take place automatically. Currently, the text content of Indexed files is read-only; in the future, the user may be allowed to modify the text for certain file types.
Do not expect that one will be able to modify a Word document within the database, including images, formatting and layout. Do not expect that one can substantially edit (significant changes in content and layout) a PDF document within the database – even Acrobat Pro is very limited in editing capabilities. The same goes for Excel, Pages, PowerPoint, Keynote, Mellel and many other applications. It would be impractical in development or license costs to DEVONtechnologies (and the resulting increased costs to users) to try to build in extensive multi-filetype editing capabilities within the DT applications, beyond those available in OS X itself. OS X keeps getting better in that respect. It’s likely that simple editing such as annotation of PDFs will appear in future DT versions.
Do expect that development will focus on the purposes and intent of the DT applications, including improved searching, database structure, speed, user assistance, scalability and interoperability with the operating system and more applications. Editing a complex Word document is best left to MS Word itself, Papyrus or perhaps the free NeoOffice application.
