Schema support

The MPDL document storing and querying system supports the document schemas Archimedes and Echo. In the near future also a subset of TEI-Lite and for URI's a subset of XPointer will be supported.

The element "pb" (page break) and "s" (sentence) are supported especially: a special fast method is used to retrieve a certain page (the fragment between two "pb" elements) in a document. And all fulltext queries within documents are executed against the element "s" and result in hits which each contains the position in the document (page number and sentence number).

Archimedes

Schema

The Archimedes schema is developed by the ​Archimedes project and could be found ​here.

Example

In the following simple example the metadata part consists of 4 elements („author“, „title“, „lang“, „date“) and the text part consists of 2 pages („pb“) with 2 paragraphs („p“) which contains 3 sentences („s“). 

<?xml version="1.0" encoding="UTF-8"?>
<archimedes xmlns:xlink="http://www.w3.org/1999/xlink">

Echo

Schema

The MPDL Echo schema is developed by the schema group of this project and could be found ​here.

Elements

An Echo document (element „echo“ with namespace „echo“) consists of a metadata part (element „metadata“) which contains the Dublin Core metadata of the document and a fulltext part (element „text“) which contains the content of the document.

Dublin Core metadata elements (namespace dcterms):

  • identifier
  • creator
  • title
  • date
  • rights
  • license
  • accessRights

Fulltext elements (with attributes in paranthesis):

  • text elements: head, div (type, level, style), p (style), pb (file), lb, cb, gap (extent), s
  • figure elements: figure, image (file), caption (style), description (style), variables (style), handwritten (xlink:href)
  • note elements: note (xlink:label)
  • quotation elements: q, quote, blockquote, set-off
  • translation elements: foreign (lang, xml:lang), reg (orig)
  • mathematical elements: var (type), num, mml:*
  • geographical elements: place, event, time
  • person elements: person
  • xhtml elements: xhtml:* : e.g. table, ul
  • other elements: expan, emph (class), ref (target), anchor (type, xlink:label, xlink:href)

Example

In the following simple example the metadata part consists of 4 Dublin Core elements („creator“, „title“, „language“, „date“) and the text part consists of 2 pages („pb“) with 2 paragraphs („p“) which contains 3 sentences („s“). 

<?xml version="1.0" encoding="UTF-8"?>

TEI Lite

A subset of TEI-Lite will be supported in the near future.

Schema

The TEI Lite schema is developed by the ​Text Encoding Initiative and could be found ​here.

A description of TEI pointers and links could be found here.

Elements

A TEI document (element „TEI“ with namespace „TEI“) consists of a metadata part (element „teiHeader“) which contains the metadata of the document and a fulltext part (element „text“) which contains the content of the document.

The following list of supported elements and attributes is only a first draft and will be finalized in the near future.

Global attributes (usable in all elements):

  • xlink:href an extension of TEI Lite

Metadata elements:

  • fileDesc, titleStmt, author, name, title, publicationStmt, date, sourceDesc, bibl
  • profileDesc, langUsage, language
  • ...

Fulltext elements (with attributes in paranthesis):

  • text elements: div, gap (extent), head, lb, lg, p, pb (xlink:href), s, seg
  • figure elements: figure
  • note elements: note
  • quotation elements: q, quote
  • translation elements: foreign (xml:lang), reg
  • mathematical elements: num, mml:*
  • time elements: date
  • xhtml elements: xhtml:* : e.g. table, ul
  • other elements: expan, emph, ref (target), anchor (xml:id)
  • ...

Example

In the following simple example the metadata part (teiHeader) consists of 4 elements („author“, „title“, „language“, „date“) and the text part consists of 2 pages („pb“) with 2 paragraphs („p“) which contains 3 sentences („s“).
