== XML-GIS Integration Project ==

''' Be careful! This site is still in progress. '''[[BR]]

=== Objectives ===
The projects aims at the implementation of interfaces between the [[https://itgroup.mpiwg-berlin.mpg.de:8080/tracs/mpdl-project-software XML-project]] and the [[http://culhis.mpiwg-berlin.mpg.de/doku.php/gis/gis_main GIS-project]].

These interfaces will enable the user to transfer between both tools.

=== Usage Scenarios ===

  * Linking of a place name in the full-text display to a map with the marked location
    - the full-text display displays a link for a place name
    - the link goes to a map display with the place
  * Integration of links to digital text documents in spatial datasets as reference
    - klick on a place on a map and get a list of links to text pages with occurences
  * Linking of prepared digital maps to specific documents as interactive illustration (travelroutes etc.)
  * Display of digital standard maps for location names
    - a URL for a location name that generates a standard map(?) for this location
  * ...

 
=== Technical Concepts ===

  - System should be based on: 
      * open source software, 
      * public free accessable databases
      * interfaces according to [[http://www.opengeospatial.org/standards OpenGIS]] and [[http://de.wikipedia.org/wiki/Representational_State_Transfer REST]]
  - Creation and saving of digital maps with permanent links
       * Saving map as static image to image-server
       * Saving dynamic map as kml, access via RESTful service
       * Saving dynamic map as querie-set for dataset selection and rule-set for map creation, access via RESTful service
  - Definition of spatial attributes for metadata of and text objects (like location names) within digital documents
    * Spatial attributes within text documents:


{{{
          <dcterms:spatial xsi:type="dcterms:Point">Berlin</dcterms:spatial>
          <dcterms:spatial xsi:type="dcterms:Box">Germany</dcterms:spatial>
          <dcterms:temporal xsi:type="dcterms:Period">1900-1950</dcterms:temporal>
          Im <time standard="1923-01">Januar 1923</time> lief Anton nach <place standard="Berlin" type="city" xlink:href="link zur Datenbank">Berlijn</place>.

}}}

    * A relevant version of the "echo-gis" modul: [[BR]]
  https://itgroup.mpiwg-berlin.mpg.de:8080/tracs/mpdl-project-content/browser/trunk/schema/echo/echo-gis.rnc
    * XML-chunks are also in Wolfgangs [[https://itgroup.mpiwg-berlin.mpg.de:8080/tracs/mpdl-
project/content/browser/trunk/schema/xml-test-files|Test-XML-File]] [[BR]]
  See the metadata and the "Im Januar 1923"-sentence at the end.
  - Automated recognition of location names within text documents with manual verification
    * Look-up with terms from local spatial database
    * Look-up in public georeferencing-service like !GoogleMaps etc.
    * Look-up in spatial gazateer service from Peter Bol
  - Manual localization (spatial referenciation) of text objects in digital maps
