Model-driven Engineering for Implementing the Iso 19100 Series of International Standards

In this paper we discuss the implementation of the ISO 19100 series of standards with use of Model-Driven Engineering (MDE) techniques. We expose how MDE is beneficial for prototyping and building an end-user application dedicated to the sharing of environmental data (especially within the context of coastal zones). We present with an illustrating example of a way to use ISO 19109, 19110 and 19117 models in order to generate a rich client application. Our work takes the geographic features, the data structures and the data display concerns into account, by means of using the various facets of the ISO 19100 series.

INTRODUCTION: Among the geographic information community, there are many applications software and numerous data formats that implement the international standards (ISO). Each application software or format comes with its own pros and cons, but unfortunately, applications software usually present as black boxes and their interoperability is generally not ensured. Data providers from a coastal zone need to populate their information systems with more and more datasets. The types of these datasets may be very heterogeneous such as maps, numerical marine information or textual fishery laws. Thus cataloguing systems should be highly flexible and generic. A standard exchange format is not sufficient for building an efficient and robust information system: the design of such information systems should ground on a standard design framework. Besides, there is a need for accessing the application structure in order to manage system interoperability. Metamodelling and more widely ModelDriven Engineering (MDE) provide tools to manage applications thanks to a decomposition in several modelling layers. The TC 211 ISO Technical Committee has specified and published the ISO 19100 series of standards that deal with geographic information. This series is composed of several specifications about data definition, data structure and metadata for georeferenced objects. The specification of the ISO 19100 series uses the UML (OMG, 2004) notation for all elements in the series and for the metamodels too, e.g.: 19109 (ISO/TC-211, 2005a), 19110 (ISO/TC-211, 2005b) and 19117 (ISO/TC-211, 2005c). In this paper we discuss the implementation of these standards within the scope of MDE techniques. We explain the benefits of using MDE for prototyping and building an end-user application dedicated to the sharing of environmental data. We show the special interest of MDE, when dealing with numerous concepts of wide application software. Our work exploits the various facets of the ISO 19100 series and addresses the metadata catalogue, the geographic features, the data structures and the data display. Our work is part of an open-
