Distributing and Synchronizing Heterogeneous Metadata for the Management of Geospatial Information Repositories

Distributing and Synchronizing Heterogeneous Metadata in Geospatial Information Repositories for Access

Agris on-line Papers in Economics and Informatics

Assessing the status and trends of the environment requires the collection, management and publication of spatially referred observations. Since many years, Long-Term Ecological Research sites in Europe collect ecological data, resulting in long-term data series. Nowadays, advanced software tools can enable discovering, accessing, and distributing collected data in a user friendly way. Based on...

A Semantic Registry Method Using Sensor Metadata Ontology to Manage Heterogeneous Sensor Information in the Geospatial Sensor Web

Efficient information management and precise discovery of heterogeneous sensors in the Geospatial Sensor Web (GSW) are a major challenge. Intelligent sensor management requires a registry service to store and process sensor information efficiently. In this paper, we propose a Sensor Metadata Ontology (SMO) to achieve a unified semantic description for heterogeneous sensors that is used to expre...

Web-Scale Normalization of Geospatial Metadata Based on Semantics-Aware Data Sources

Geospatial metadata are largely denormalized inasmuch as resource descriptions typically accommodate property values as plain text. Hence, it is not possible to bring multiple references to the same entity (say, a keyword from a controlled vocabulary) under the same umbrella. This practice is ultimately the main source for the heterogeneities in metadata descriptions by which geospatial discove...

Celebrating 10 Years of Government of Canada Metadata Standards

As the Dublin Core Metadata Initiative celebrates its 15th anniversary, the Government of Canada (GC) celebrates its 10th year of making information easier to find. The Government of Canada officially adopted the Dublin Core as its core metadata standard for Web resource discovery in 2001. Soon the Government of Canada started to develop domain-specific metadata beyond Web and resource discover...
