Overview to Document file Header:
All documents handled by DocuWare have a header which contains the index data entered for this document. Index data which was entered before storing a document is written into a database as well as the header of the document. This double management of data provides you with maximum security. Even in the case of a total database crash, your documents and index data remain accessible.
Header in DocuWare 5 mode:
All documents in DocuWare 5 mode have their own header file in XML format. If the document is stored in the file cabinet, this header file refers to the entire document, i.e. to all document pages. In DocuWare 5 documents that are in the basket have a header file for each document page.
The size of the header file is not subject to any restrictions.
Header in DocuWare 4 mode:
B/w TIFF documents that were created by DocuWare have the header within the document file. With files of other formats this is not possible. In these cases, the header has to be written to its own file. Baskets and file cabinets in DocuWare 4 mode have one header per document page; where TIFF documents were created by DocuWare this is in the document file, with other formats there is a separate header file.
The size of the header is 1024 Bytes for b/w Tiff documents and foreign formats. If a document is stored in a file cabinet, its index criteria is written into this area. The exception is the Memo Field of a file cabinet. This information is attached to the end of a document file for a b/w Tiff document. For foreign formats, the Memo Field is stored at the end of the header file.
It may not be possible for file cabinets with numerous database fields and a keyword field, for all keywords to be written into the header. Keywords are only then written into the header after all other database fields have been captured, which means they might not be included completely. This must be remembered in particular when pre-indexing documents in a basket.
