METADATA FOR WEATHER DATABASES AT SMHI: XML-storage of weather metadata

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
SMHI maintains large volumes of meteorological, hydrological and oceanographic data (MHO data) in many separate databases. Each database contains different data from different time periods in different formats. A major problem is to locate relevant databases, understand how to access them, and how to correctly interpret the data. Most of the database systems provide metadata(*) but we lack a central tool that can search across all available information resources.
As a first step towards a central metadata tool, SMHI adopted the FGDC standard (Federal Geographic Data Committee **) for electronic documentation of our MHO databases. However, collecting, formatting, and entering metadata is tedious work. The next step is to develop harvesting agents that automatically collect metadata from the separate database systems and organise the metadata according to the FGDCs XML-based metadata model . The XML-data needs to be organised and stored in an efficient manner. Finally, users should be able to search the harvested metadata using an intuitive but flexible GUI.

Project Proposal: XML-storage of weather metadata
The proposed Master Thesis is to investigate and evaluate techniques for storing geospatial metadata in XML-format (according to the FGDC standard). The final report should include:
- a review of existing techniques for storing XML-data.
- an evaluation of commercial and open-source solutions for XML-storage with a focus on support for metadata search.
- documentation of an implementation of a select storage-solution
- discussion of the solution.
