Media Adaptors bridge existing concrete document formats into the system.
Behaviors operate on an abstract definition of the document
presented by media adaptors, enabling them to operate
across all concrete types without modification.
For example, the same few lines of code that implement the
hyperlink behavior for HTML work on scanned page images, ASCII,
manual pages, and document types yet to be supported (or invented).
Native support of a document format with a media adaptor yields
several benefits. The document trees provide a uniform data structure
for services such cross-type text searching and
any-to-any document conversions.
As opposed to OLE and other architectures that
simply display another application within their own window, behaviors
can deeply manipulate documents, sorting tables and incrementally
reformatting to place annotations between lines, for instance. Native
support is better than conversions, such as to HTML, because no one
document format (especially HTML) can fully capture the semantic
structure of the source format, and so information is lost;
conversions have to be maintained as the original document is updated;
and conversions may not be conveniently available when browsing other
- PDF - Based on PDF 1.5.
Annotatable with built-in tools.
- Scanned paper: XDOC - select and paste, annotate with incremental reformatting; based on ScanSoft OCR
- Scanned paper: PDA - select and paste, annotate with incremental reformatting; based on Caere's OCR
- HTML - HTML 3.2 (TABLE, FRAME, FORM) with extensive correction of erroneous markup,
- UNIX Manual Page - reads [tn]roff source, optional outline display
- TeX DVI - using Type 1 versions of TEX fonts only (no bitmaps)
- Apple II AppleWorks word processing
- native Multivalent hub - lists behaviors to applicable to all documents, those of particular genre, or single document
- ASCII - UNIX, Macintosh, and Windows line endings
- Perl POD -
[for developers, it's an example of how to convert to HTML internally, on demand]
.class - show methods and fields from compiled Java bytecode
- Zip - see contents, sort by name/size/date, extract files
- local directories - navigate around directory tree, sort by name/size/date
FTP directories -
marks up files and directories with links, automatically displays README
- hex dump - also extract strings from binary
- raw image - displays Java built-in types: PNG, JPEG, GIF.
Also supports XBM.
Participates in the Java Image I/O framework,
so you can add new image types
simply by adding a new JAR; for instance,
the Java Advanced Imaging API
adds JPEG 2000, TIFF, BMP and WBMP.
