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"?>

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

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

Schema

TEI provides customizations for different purposes. The MPDL project supports a subset of TEI Lite which is widely used and includes basic elements for simple documents. Also some useful elements (which are part of the TEI schema with all modules) and MathML and SVG (which are part of the TEI schema with all modules plus external additions) are supported.

A description of TEI pointers could be found here.

Elements

TEI Lite (with attributes in paranthesis):

metadata elements: fileDesc, titleStmt, author, name, title, publicationStmt, date, idno, availability, sourceDesc, bibl, profileDesc, langUsage, language
text elements: div, gap (extent), head, lb, lg, l, p, pb, s, seg
link elements: ref (target), ptr (target), anchor (xml:id)
figure elements: figure
note elements: note (place)
quotation elements: q, quote
translation elements: foreign (xml:lang), reg
terminology elements: term
name elements: name (type="place"), (type="person"), name (type="organization")
time elements: date
mathematical elements: num
other elements: hi (rend), expan, emph, choice, orig, abbr, sic, corr

TEI

text elements: pb (facs)
figure elements: figure (facs)
name elements: placeName (type), persName
other elements: ex, am

Additional

MathML elements: m:*
SVG elements: svg:*
XHTML elements (e.g. table and list elements): xhtml:* (planned in future)

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“) and a formula in MathML. The second line (beginning with "<?oxygen RNGSchema=") could be omitted when no additional TEI elements (e.g. MathML) are used.
