Advancements in DICOM Documentation: Transition to XML Format and Future Directions

In 2003, the Ad Hoc Publishing Committee initiated a transition towards DICOM documentation in XML, culminating in 'proof-of-concept' drafts for several parts of the standard. Following a stagnation due to the loss of key contributors, efforts resumed with funding from NEMA to continue conversion from Word to DocBook XML. Significant progress includes error correction, relative path adjustments, and the establishment of a portable build environment. Upcoming work involves enhancing DICOM-specific schema, improving cross-referencing, and developing a database for better table management, with a timetable set for the next DICOM release.

  1. DICOM in XML Where we’re headed

  2. Background • In 2003, the Ad Hoc Publishing Committee created ‘proof-of-concept’ drafts of Parts 3, 6, 12, and 16 • Base standard in DocBook XML • DICOM-specific tables for IODs, Modules, Macros, Data Dictionary, Templates, Context Groups • Style sheets for HTML, Chunked HTML (help files), PDF • Lost principle workers in 2004, progress stagnated • NEMA funded student intern to continue conversion

  3. Completed Work • Starting from earlier test conversion of Parts 3, 6, 12, 16 • Fixed errors in the converted XML source • Changed environment specific path names to relative ones • Added missing tables • Portable build environment created (single download) • Ant scripts/Java/xmlproc used to facilitate efficient processing in various operating environments • Includes entire processing pipeline (DICOM → DocBook → Output in various formats, including cross reference links) • Build process to output proven in the Linux and Windows XP operating environments • Prototyped the use of a Subversion (SVN) data repository for source control/configuration management

  4. Current Work (in Progress) • Completed the initial rough conversion from Word to DocBook XML for all remaining Parts (draft 2005 version) • Correcting errors in the newly converted XML source • Updating existing XML source for Parts 3, 6, 12, and 16 to latest draft 2005 version

  5. Work Needed for Publication • Convert WMF drawings to portable graphics files (SVG) • Compare outputs against the original word documents to insure correctness

  6. Suggested Additions • DICOM specific schema for Part 4 and perhaps other tables • Greater cross-referencing between parts • Set up XCatalogues to simplify organization (prototyped) • Use a database to manage DICOM-specific tables

  7. Proposed Timetable • Next DICOM release (2005/6) still in Word format • Shortly after next release, make unofficial XML version available, base on Ad Hoc group schemas • Switch officially to XML version in following (2006/7) release, dropping Word version • Future schema changes • Would be part of the periodic release cycles • Should include xslt scripts used to convert to the new schemas
