Preparing a yummy soup and implementing successfully a SDI have resemblances. Both require to follow recipes that contains two lists. The first is the list of ingredients (a suite of standards for data, metadata and services); the second is the directions to mix them (a best practice to interoperate). There are different kinds of soups depending on the culinary tradition (or influential standards body). They differ mainly in the list of ingredients because the tradition marks what is in the list. But, what about when we prepare fusion cuisine? That is, what about when we develop a geospatial project based on standards elaborated by different standardisation bodies? The Linked Map project is an example. The Linked Map project (http://linkedmap.unizar.es/) is a subproject of the European FP7 PlanetData project (http://planet-data.eu/). One of its aims was to demonstrate the usefulness of Linked Data for developing an infrastructure for geospatial data QA based on crowdsourcing techniques. The infrastructure included services such as provenance data capture, data integration with official data sources, and data visualization in maps. The Linked Map project faced several scenarios that involved the joint use of standards at data, metadata and service level elaborated by different standardisation bodies. These scenarios included the conversion of data stored in OGC-compliant spatial databases into Linked Data by using the W3C R2RML mapping language, the capture of provenance metadata associated with workflow execution using a W3C PROV extension aligned to the ISO 19115 lineage model, and the use of IETF Web Links headers in OGC WMS responses to link to resources related to the map content. This presentation will present our experience in joint interoperability of emerging and established standards at different levels. Our main insight: the lack of agreed directions for mixing the new ingredients, the emerging standards of W3C and IETF. Hopefully our community has begun to be aware of it. The joint W3C/OGC working group is a good step in fixing the consistency of the standards bodies soup.
