  8. 8. About the Author • Independent consultant focusing on DITA analysis, design, and implementation • Doing SGML and XML for cough 30 years cough • Founding member of the DITA Technical Committee • Founding member of the XML Working Group • Co-editor of HyTime standard (ISO/IEC 10744) • Primary developer and founder of the DITA for Publishers project • Author of DITA for Practitioners, Vol 1 (XML Press) • More DITA 1.3 accepted proposals than any other TC member Contrext, LLC 8
  9. 9. DITA VERSION 1.3 ACTIVITY Contrext, LLC 9
  10. 10. DITA 1.3 Status • DITA 1.3 features are frozen as of May 2014 • Public draft of final 1.3 specification for OASIS final approval process available soon • Approval targeted for mid 2015 • Implementation in Open Toolkit under way (OT 2.x, DITA Community organization) Contrext, LLC 10
  11. 11. What Can I Do Today? • New vocabulary immediately usable – Map and topic types and new domains are normal DITA specializations – DITA 1.3 vocabulary packaged as OT plugin for convenience – Spec is stable—markup design unlikely to change between now and final approval – OT 2.x is 1.3 support release. Many 1.3 features already implemented – Most vocabulary also supported by OT 1.x plugins • New architecture can be implemented as preprocessing for DITA 1.2 processors Contrext, LLC 11
  12. 12. Reminder: Always Backward Compatible • All DITA 1.x versions must be backwards compatible with earler 1.x versions • DITA 1.3 completely backwards compatible – All DITA 1.0, 1.1, 1.2 documents are valid 1.3 documents – Behavior of documents should be the same Contrext, LLC 12
  13. 13. QUICK OVERVIEW OF NEW DITA 1.3 FEATURES Contrext, LLC 13
  14. 14. Lots of New Vocabulary • MathML and SVG integrations • Troubleshooting: new topic type, note type, task elements • UX window display details map element and <revisionid> attributes • Release management metadata • Learning and training enhancements • @deliveryTarget conditional attribute • <line-through> and <overline> in highlight domain • New <div> base element type • Elements for tagging XML markup • New <sort-as> element • New table attributes for layout control and accessibility • @cascade to control metadata propagation in maps • More… Contrext, LLC 14
  15. 15. Architectural Enhancements • Scoped keys – Same key reference can resolve to different topics or text in different parts of a map – Enables cross-deliverable linking • Branch filtering – Apply different filtering rules to different parts of a map – Automates replication of map branches for different sets of conditions • “this topic” fragment identifier: “#./fig-01” • Cross-deliverable links Contrext, LLC 15
  16. 16. Not Even Talking About • RELAX NG as master vocabulary grammar format • Many small-but-important enhancements to base content models • Specialization enhancments (use structural types as though they were domains) • Specification improvements • Stuff we considered but didn’t put in for various reasons Contrext, LLC 16
  17. 17. ARCHITECTURAL ENHANCEMENT: SCOPED KEYS Contrext, LLC 17
  18. 18. DITA 1.2 Keys • Indirect addressing for topics: – Assign keys to topics within maps – Refer to keys in topics – Keys resolve through map – Same key can resolve to different topics in different maps – Essential for re-use • In 1.2, keys are global within a given publication (root map) – Every reference to a key must resolve to the same topic or text – Limits creation of multi-product or multi-language publications Contrext, LLC 18
  19. 19. DITA 1.3: Key Scopes • Named scopes within maps • Unqualified key references resolve to key in current scope • Key references can be qualified with scope names: scope1.key-one, scope2.key-one • Higher maps can override keys defined in scopes • Same key referenced in different scopes can resolve to different topics • Same topic used in different scopes within same map can link to different targets • Applies to conref, xref, topicref, etc. Contrext, LLC 19
  20. 20. Scoped Key Use Cases • Multi-product or multi-language publications – Each product or language is a different scope – Different text or topics or images for same key in different product or language context • Combine separate publications into a single publication – Each publication is a separate key scope and defines its own keys – No interference between keys defined in each publication Contrext, LLC 20
  21. 21. Cross-Deliverable Links • Define another publication’s root map as a key scope in your map – Target publication is a “peer” to your publication – Processors don’t have to process the target map when processing your map • Can link to keys defined in the target publication using scope-qualified key references • Enables generation of deliverables with working cross-deliverable links, e.g.: HTML-to-HTML, HTML-to-PDF, PDF-to-PDF, PDF-to-HTML Contrext, LLC 21
  22. 22. ARCHITECTURAL ENHANCEMENT: BRANCH FILTERING Contrext, LLC 22
  23. 23. DITA 1.2 Filtering • Filtering conditions apply only to whole publication • No way to have different conditions applied to different parts of a map • Can lead to complex and hard-to-manage conditions Contrext, LLC 23
  24. 24. DITA 1.3: Branch Filtering • Point to DITAVAL files from within topicrefs • DITAVAL applies to that branch of the map • For a single branch, can have multiple DITAVAL references – Each DITAVAL produces a new copy of the branch filtered according to that DITAVAL – Avoids need to maintain copies of map branches with only different filtering • Can control how names in duplicated branches are constructed Contrext, LLC 24
  25. 25. Branch Filtering Use Cases • Multi-platform publications: – <chapter keyref=“installation”> <ditavalref keyref=“ditaval-osx”/> <ditavalref keyref=“ditaval-win”/> <ditavalref keyref=“ditaval-lin”/> <topicref keyref=“inst-overview”/> … </chapter> • Multi-audience publications • Multi-product publications Contrext, LLC 25
  26. 26. NEW VOCABULARY Contrext, LLC 26
  27. 27. SVG Integration • Inline SVG graphics – <svg-container> • Can pull in SVG from non-DITA XML files – <svgref> Contrext, LLC 27
  28. 28. MathML Integration • MathML domain: – <mathml> element contains <m:math> – Can link to <m:math> elements in non-DITA XML files: <mathmlref> • Equation domain: – Elements for identifying semantic equations: • <equation-inline>, <equation-block>, <equation-figure> – Can control equation numbering • <equation-number> – Can have alternate forms of the equation: MathML, image, etc. Contrext, LLC 28
  29. 29. Troubleshooting Support • New topic type: troubleshooting – Provides problem/cause/solution structures • New elements for use within tasks: – <steptroubleshooting>, <tasktroubleshooting> – Clearly identifies troubleshooting-specific information • New “trouble” note type for highlighting troubleshooting-related notes Contrext, LLC 29
  30. 30. UX Window Control • Specifically for online help • Within maps: – Define size and position details of windodws to use for showing online help – <ux-window name=“win-01” width=“400” height=“600” > • Within topics: – Reference named windows from <resourceid> elements in topics – <resourceid appid=“myapp” ux-windowref=“win-01”/> Contrext, LLC 30
  31. 31. Release Management Metadata • Metadata for maps and topics – <change-historylist> – <change-item> • Lets you capture details about a specific change to the map or topic: – Who, what, when, why – References to issue-tracker issues • Can be extended with additional metadata Contrext, LLC 31
  32. 32. Learning and Training Enhancements • New learingObjectMap and learningGroupMap map types • New learning2 domain for interactions (assessments): – Allows block elements in questions, answers, and feedback – Same semantics and question types as DITA 1.2 learning domain – Can be used with 1.2 learning domain Contrext, LLC 32
  33. 33. @deliveryTarget Conditional Attribute • Lets you have deliverable-specific content: – PDF, EPUB, HTML, online help, etc. • Specialization of @props • Includes sample subject scheme map that defines a set of typical values • Can use any values you want Contrext, LLC 33
  34. 34. Highlight Domain Enhancements • New element types: – <line-through> – <overline> • Completes the set of line-based highlighting (underline, overline, line-through) • Note: Can use existing @status=“deleted” to indicate deletions Contrext, LLC 34
  35. 35. XML Markup Tagging • XML domain • Elements for tagging mentions of XML elements, attributes, etc. • Useful for documenting XML vocabularies • Used by the DITA 1.3 spec • XML domain specializes “markup domain” – General elements for indentifying any kind of markup-related names: <markupname> Contrext, LLC 35
  36. 36. New <div> Base Element Type • Like DITA 1.2 <sectiondiv> • Can go in body or section • Specialization base for learning2 elements • No semantic other than containment Contrext, LLC 36
  37. 37. SUMMARY Contrext, LLC 37
  38. 38. Reuse Support Features • Scoped keys and branch filtering satisfy most of the reuse requirements not met in DITA 1.2 • “This topic” fragment identifier makes links within conrefs work properly • Branch filtering makes multi-product or multi- language or multi-audience publications possible • Cross-deliverable linking allows flexibility in packaging of content into deliverables Contrext, LLC 38
  39. 39. Vocabulary: Key Requirements, Relevant Standards • Integration of MathML and SVG aligns DITA with HTML5 and EPUB3 • Troubleshooting and release management markup addresses important Technical Communication requirements • Learning2 domain makes question and answer markup useable for typical Publishing use cases • UX enhancements important for online help delivery Contrext, LLC 39
  40. 40. In Short • DITA 1.3 fills in important feature holes left in DITA 1.2 • Iterative improvement in vocabulary • No changes to existing semantics, processing rules, etc. • Key scopes and branch filtering critical for authors but challenging for CCMS and authoring tool vendors • Highlights importance of Information Architect role within writing teams Contrext, LLC 40
