The FLORID-MONDIAL Case Study

The MONDIAL database has been compiled from geographical Web data sources listed below using the F-Logic system FLORID:

• CIA World Factbook,
• Global Statistics which has been collected by Johan van der Heijden,
• additional textual sources for coordinates,
• the International Atlas by Kümmerly & Frey, Rand McNally, and Westermann,
• and some geographical data of the Karlsruhe TERRA database.

The data extraction and integration process is described in the report

• Information Extraction and Integration with FLORID: The Mondial Case Study.
  Wolfgang May; Technical Report 131, Institut für Informatik, Universität Freiburg, 1999.

F-Logic: Compilation of the Database

In the following list, red files are result files :

• Extraction Programs
  • Data from Global Statistics "mondial-gs.flp"
  • Country Data from CIA World Factbook (1996) "mondial-cia.flp"
  • Organizations Data from CIA World Factbook (1996) "mondial-orgs.flp"
  • Data from qiblih (Geographical Coordinates) "mondial-qiblih.flp"
  • Country Codes etc. "mondial-codes.flp"
• Sources in F-Logic Representation
  • Data from Global Statistics "mondial-gs-facts.flp"
  • Country Data from CIA World Factbook (1996) "mondial-cia-facts.flp"
  • Organizations Data from CIA World Factbook (1996) "mondial-orgs-facts.flp"
  • Data from qiblih (Geographical Coordinates) "mondial-qiblih-facts.flp"
  • Country Codes etc. "mondial-codes-facts.flp"
  • the original TERRA database "mondial-terra-facts.flp"
• Integration Programs and Results (needs all *-facts.flp)
  • Integration program "mondial-integra.flp"
  • Dump of the integrated database "mondial-all-facts.flp"
  • Complementary data "mondial-addprovs.flp"
  • Data cleaning program "mondial-clean.flp"
  (needs mondial-all-facts.flp and mondial-addprovs.flp)
  • Cleaned data in an OO schema "mondial-oo-facts.flp"
  • program for outputting cleaned data in Florid Frame Format "mondial-export.flp"
  • Cleaned data in Florid Frame Format "mondial-frames.flp"

Generating the Relational Representation:

The Database training "Praktikum: Datenbankprogrammierung in SQL/Oracle" at the IFI uses the relational version of the MONDIAL database:

• Mapping to a Relational Schema (needs mondial-oo-facts.flp)
  • Mapping program "mondial-rel.flp" (needs mondial-all-facts.flp)
  • Relational data (Datalog) "mondial-rel-facts.flp"
• Mapping to Oracle (needs mondial-rel-facts.flp)
  • Mapping script (perl) "mondial-rel-facts2sql.pl"
• Mondial for Oracle
  • The SQL sources for Mondial can be found at the Mondial homepage. (Note that Mondial has been revised since then)
• Documentation
  • The documentation for Mondial can be found at the Mondial homepage. (Note that Mondial has been revised since then)

MONDIAL in XML

• Conversion of sources from F-Logic to XML
  • Mapping Sources from .flp to XML "mondial-export-sources.flp" (needs mondial-*-facts.flp)
  • The Mondial database in XML can be found at the Mondial homepage. (Note that Mondial has been revised since then)
• The case study on information integration in XML continues here

The MONDIAL database has been stimulated by the TERRA database and the SQL training of the Institut für Programmstrukturen und Datenorganisation der Universität Karlsruhe. Using Florid, a new database has been generated, from the above data sources.

MONDIAL and the IIF Oracle training is freely available for research and educational purposes under the condition that the origin of MONDIAL is mentioned in all publications and documentation.
