Projects
- HUMBOLDT Commons
The HUMBOLDT Commons are a set of libraries that contain common functionality needed by multiple components from the Framework and applications from the Toolset. Specifically, it includes the
Context, theMediatorComplexRequest, severalWorkflowstructures and theGeo Ontology Mapping Languageclasses.... - HUMBOLDT FrameworkThis project collects the HUMBOLDT Service Integration Framework subprojects, specifically:
- the Mediator Service (MS), a harmonisation workflow execution engine,
- the Workflow Construction and Design Service (WDCS), an harmonisation needs analysis and workflow construction component, ...
- Conceptual Schema Transformer
The Conceptual Schema Transformer (CST) is a library that is able to apply a schema transformation to a geodata set (expressed in a specific source Application Schema (A)) in order to provide a geodata set (expressed in a specific target Application Schema B). A schema mapping between schema A and schema B has to be defined beforehand in order to accomplish the transformation. ...
- Edge Matching Service
The Edge Matching Service is a Web Processing Service (WPS) implementation of a service that aligns edges and points of vector geometries so that they will be gapless. It has two modes of operation - Align-to-Reference and Distribute-Errors, which can be used when there is no reference data set that can be used as "ground truth"....
- HUMBOLDT Specification
In this project, the external interfaces and main data structures for the HUMBOLD Framework are specified.
- Information Grounding Service
The Information Grounding Service is the HUMBOLDT component responsible for the discovery of geospatial data services. It does no replace existing catalogues but serves as a catalogue of catalogues being capable of discovering a huge number of different resources covering different administrative areas and registered to different catalogues. Furthermore, the Information Grounding Service discovers not just the datasets which fulfil a list of constraints; but also those can be transformed by other HUMBOLDT components in order to satisfy it....
- Mediator Service
The Mediator Service is a service component that executes transformation requests. It provides standard interfaces such as WCS, WPS, WFS and WMS for triggering these transformations and for returning results. It makes use of other components to get input to this process, such as Download Services, WEb Processing Services and HUMBOLDT Services (Context Service, WCDS)....
- Workflow Design and C. Service
The HUMBOLDT Workflow Design and Construction Service enables users to register and compose geoprocessing functionality into workflows / service chains. Such components can either be encapsulated as OGC WPS or directly implemented on the platform on which the HUMBOLDT Mediator Service is deployed. Further, it provides the functionality to support automated harmonisation. ...
- HUMBOLDT Harmonisation ToolkitThe HUMBOLDT Harmonisation Toolkit includes applications that can be used by geodata experts to specify conceptual models and to define the transformation in between the conceptual schemas. The toolkit includes the following applications:
- The HUMBOLDT Model Editor,...
- HUMBOLDT Alignment Editor
HALE is a tool for defining and evaluating conceptual schema mappings. The goal of HALE is to allow domain experts to ensure logically and semantically consistent mappings and consequently transformed geodata. Furthermore, a major focus is put on documentation of the schema transformation process and its impacts, e.g. in the form of lineage information attached to the resultant transformed data....
- HUMBOLDT GeoModel Editor
The HUMBOLDT GeoModel Editor is an UML-based, visual editor specifically designed for developing complex application schemas for geodata. It comes pre-packaged with models of all important standards and allows you to export created models in various formats, from ecore over XMI to GML application schemas. ...
