1. TEI technology in Oxford projects

As a TEI Consortium host and provider of editorial services to the TEI, the University of Oxford naturally has many projects and services which use the TEI Guidelines.

The OUCS Research Technologies Service (RTS) aims to provide a centre of expertise supporting the development of research e-infrastructure. The RTS seeks to lead or collaborate on projects that pilot digital technologies on behalf of the University. Many of these projects use TEI XML where appropriate.

2. OUCS Website

  • Oxford University Computing Services Website: http://www.oucs.ox.ac.uk/
  • Subversion-based version control
  • Preview/Publish system
  • Many files split at top-level <div> elements for display
  • Currently processed with AxKit + XSLT

11. OpenOffice <-> TEI Stylesheets

  • OpenOffice is a free Office suite of tools (e.g. Word-processor, Spreadsheet, Presentations, Database, Drawing)
  • Reads and writes many formats (inc. Microsoft), but also including arbitrary XML if you create XSLT to map it to its own ODF schema
  • Sebastian Rahtz has created stylesheets to enable:
    • Opening TEI XML files in OpenOffice
    • Saving OpenOffice files as TEI XML
  • Limitations of presentational markup
  • Freely available from TEI SourceForge Website

12. OpenOffice, SaveAs TEI XML

13. TEI ISO

  • Project with ISO, OUCS, TEI, Brigham Young University, and the Max Planck Digital Library
  • International Standards Organization: production of standards documents
  • TEI ODD for documenting a schema to store these standards as TEI XML
  • A suite of XSLT to allow lossless conversion to and from various word-processing systems (e.g. MS Word)
  • This ability to round-trip from presentational markup may also be available to other users
  • http://tei.oucs.ox.ac.uk/TEIISO/

15. Holinshed's Chronicles

  • Tudor Chronicles of England, Scotland, and Ireland
  • Popular source for Shakespeare, Spenser, Daniel, Drayton
  • Two Editions: 1577 and 1587(revised and significantly expanded)
  • Producing a print, old-spelling, annotated critical edition
  • An electronic full-text copy of 1587 exists in EEBO-TCP
  • EEBO-TCP has been commissioned to create an electronic full-text version of 1577 edition
  • We will be producing something to allow them to fuzzy-match paragraphs from one to another, using stand-off linking, to assist them in making their comparisons
  • We wrote an EEBO-TCP markup to TEI P5 XML transformation in XSLT as a first step

  • Provide access to these in Manuscriptorium in their own languages and their own virtual interface
  • To standardise metadata on a variant of TEI P5 XML where possible
  • All we implement should work together seamlessly

29. William Godwin Diaries

  • William Godwin:
    • 1756-1836, philosopher, writer, political activist,
    • husband of Mary Wollstonecraft, father of Mary Godwin (aka Wollstonecraft Shelley).
  • Inter-Departmental:
    • Politics, Statistics, Computing Services, Bodleian Library, etc. Project Staff:
    • Dr Mark Philp, David O'Shaughnessy, two students, + others
  • Objectives:
    • research to identify people mentioned in the 48 years of diary;
    • provide a searchable cross-referenced electronic edition alongside digital images of the diary
  • Started in October 2007, it coincided with initial release of TEI P5 and immediately benefited from new features.

31. Diary + XML

32. The odd Godwin ODD

  • Created a customised TEI ODD for the Godwin project, this included:
    • removal of many TEI modules and elements
    • addition of new syntactic sugar elements
    • providing closed attribute value lists
  • New elements:
    • should be added in new namespace
    • choice between that and canonicalisation (by XSL)
  • ODD provides:
    • schemas (DTD, RelaxNG, W3C Schema)
    • project specific documentation
    • option for internationalisation
    • useful assistance in chosen editor

33. Godwin ODD

34. <person>, <persName>, and people

  • Pointing from the c. 64000 instances of <persName> elements to <person> elements stored in separate files
  • Around 10000 distinct values of <persName> Instances of multiple @ref values, was corrected in most recent TEI P5 release, but how to display?
    <persName ref="#BR01 #BR02 #BR03">The Browns</persName>
  • Person records follow a strictly limited template
  • Submit person file and it instantly appears on SVN-driven project website in indices
  • Almost identical system will eventually be used for identifying texts and places

35. Person File

36. <person> and <persName>

37. Transforming Godwin

  • Unlike many editions, researchers interested more in social relationships, frequencies of contact, and statistics
  • Lists of element/attribute combinations produced to assist proofreading and editorial standards
    • lists by frequency
    • lists by distinct-value
    • lists by year
  • XQuery in eXist will be used for front-facing site
  • For project site: XSLT2-based grouping with xsl:for-each-group to create statistical lists
  • Transformations to CSV for people in Statistics Department
  • interested in networked relations of contacts in meetings

38. xsl:for-each-group

39. Rendered Generated List

40. Project Work

  • Project working practices...practices working
    • scheduled coding sessions
    • project blame sheets
    • group-written internal editorial policies
  • 2 Days Training:
    • Customised TEI XML,
    • oXygen,
    • Tortoise SVN
  • Subversion-based website: they commit, anyone reads
  • Project evolution:
    • new additions/customisations,
    • finer distinctions based on generated lists,
  • Feedback Loop: Lather, rinse, repeat
  • Fine line between freedom to change and locking down practices -- project has been impressed with TEI flexibility

41. Future of the Godwin Project

  • Project to complete in 2010, future still open
  • Website to be hosted by Bodleian
  • Website will allow access to underlying XML
  • Circular navigation & dynamic record aggregation
  • Places and textual works to be encoded similar to people
  • Leverage social networking technology? FOAF Browsers?
  • Javascript timelines of certain events
  • Google Maps API could be used for zoomify-like dynamic zooming of images Bodleian is taking of the diary

42. TEI-Related Projects at Oxford -- Conclusions

  • We tend to get involved with TEI-related project which:
    • are of small to medium scale projects
    • where people need a single defined workpackage
    • where we provide advice, support, or schema Design
    • where we feel it will benefit other users (so we release the output with an open licence)
    • where people have approached us before they write their funding bid instead of after they get the money
