Biography
Former engineer of the french national mapping agency, Jean-Loup Delaveau is a 13 years experienced in the field of geodata management.He drove projects in the fields of thematic data specification for regional SDI, of webmapping applications and GIS with the permanent concern of the data lifecycle. He has been involved in the INSPIRE directive implementation for 6 years in the french ministry of ecology and sustainable development and now as founder of SPRINGEO. He aims to implement thematic INSPIRE download webservices using his adaptative and schema-driven transformation framework.

Abstract
Fit2INSPIRE a Sustainable Path to Interoperability

SPRINGEO is a recent French startup developing on-demand and thematic download web-services for providing interoperable geospatial data. Its service helps existing spatial data infrastructure (SDI) to achieve INSPIRE conformity at the data level, as well as to boost their Opendata projects by data standardization. SPRINGEO has developed a complete service called "fit2INSPIRE" using opensource tools in an innovative manner : we adapt tools to existing databases rather than relying on potential very complex data transformation workflows. The "fit2INSPIRE" framework has been set up with the concern of the balance between data re-usability, implementation and maintenance costs optimization, and INSPIRE interoperability requirements. By re-usability, we consider that a unique endpoint at regional level that delivers harmonized data from an agregrated database is much more effective than a multiple files approach. fit2INSPIRE provides indeed direct access to conformant data using webservice technologies. This approach is in the INSPIRE directive "spirit" in the sense that it delivers data streams that can be consumed by different applications and devices. Exchanged GML messages remian transparent for application users. The fit2INSPIRE framework is thematic oriented to reduce development costs. First, the development of any new INSPIRE webservices is shorten by a schema driven development process. Secondly, we have choosen a noSQL database for its flexibility in data schema management. noSQL databases store data in JSON documents which are fairly closed to expected GML output. That simplifies data bindings and data serialization. Finally, our technology suits to agregate multiples ressources in cloud environment in order to decrease exploitation and maintenance costs. How does fit2INSPIRE work? Our two steps standardize & serialize method enables providing INSPIRE data through a WFS 2.0 download service in a sustainable way. The first step needs a specific adaptation to data sources whereas the second one is generic. ETL connectors using Talend transform data souces in thematic JSON documents. Once they are stored in the target noSQL datastore, data automatically becomes INSPIRE conformant.
