    With its Web-based software solution Preludio, Disy Informationssysteme GmbH offers one of the most powerful and at the same time user-friendly solutions for standards-compliant metadata management in Spatial Data Infrastructures (SDI). Preludio supports editing, discovery, management and exchange of metadata for data, services and applications in an SDI. In this article, we describe the most important features of Preludio. Furthermore, we describe ongoing research and development in the European Research project eENVplus aiming at powerful new tools for multi-thesaurus management for metadata.

    Werkzeugunterstützung für ETL-Prozesse mit Geodaten

    Data Warehousing and Spatial Data Infrastructures (SDI) are becoming more and more accepted in public administrations, also in environment administrations and geo data authorities. Hence, the importance of professional ETL (extract -transform -load) processes for data acquisition, integration, cleansing, and storage is also growing. Though there are numerous ETL tools on the market since many years, not many of them provide comfortable functionalities for dealing with geo data. Hence Disy evaluated a couple of widespread Geo-ETL tools (Talend Open Studio, FME, GeoKettle, Oracle Data Integrator) with respect to their suitability for professional and sustainable ETL projects in eGovernment SDI contexts. It turned out that Talend Open Studio is in general very favorable, but still has weaknesses regarding geo data integration (Spatial ETL). So, Disyhas developed a new Talend plug-in for Spatial ETL –which is presented in this paper.
