Why MigCat ?
- More and more public geographic datasets are published using open data platforms when they should use an Inspire platform.
This can be explained by a lack of knowledge of Inspire obligations by some public authorities,
but also by the complexity of the current technical framework.
- In France, beyond traditional applications such as spatial data portals, the Inspire data catalogs are not sufficiently used
by professional or consumer applications.
- Thus, when an authority makes the effort to publish its data in this infrastructure, they are insufficiently valued.
Again, the complexity of the technical framework, especially for Web developers that are not GIS-experts, slow down the development of applications using the infrastructure.
- Therefore, in practice, Inspire competes with the Open Data as the objectives of both actions are close and should be more complementary than competitive.
- Making this statement, this reflection, called MigCat, is to provide a data publishing technical framework that :
- simplifies publishing datasets for public authorities, a priori, not familiar with the current technical framework of Inspire and
- facilitates the use of the infrastructure by Web programmers that are not GIS-experts
- The 4 fundamental ideas in MigCat are:
- simplify the mechanisms of data publication and discovery,
- rely on the web standards rather than on GIS standards where relevant,
- encode a number of MD elements (keyword from a controlled vocabulary, Specification, Conditions applying to access and use, Limitations on public access) using the URI mechanism
- while complying with the legal requirements of Inspire.
What is MigCat ?
MigCat is a data catalog management method based on the requirements of the Inspire directive that defines :
MigCat is also a “quick and dirty” ongoing prototype to illustrate the method that allows:
To test the, see http://migcat.fr/demo-en/.
- to manage a local data catalog (creating, deleting, modifying metadata files),
- to define in a registry the lists of codes used to manage metadata,
- to import existing data catalogs,
- to query catalogs throw discovery services,
- to view & download the datasets throw view / download services.
This method can be used in 2 ways :
It would be usefull to standardize the method !
- To build new simpler catalogs, particularly for non-GIS users
- To expose existing CSW catalogs to web programmers
Are there other initiatives ?
