5. METADATA MANAGER For metadata creation and management, a fundamental role is played by the tool adopted. In SITR-IDT this tool, which consists of dedicated software, is still being developed. It is a client desktop working on the local SITR-IDT intranet and connected via Open Database Connectivity (ODBC) with the Oracle metadata database. Software was created at the beginning of the SITR-IDT project to access and manage the metadata database. Its conceptual model was structured according to the ‘IntesaGIS’ hierarchical data structure. SITR-IDT’s metadata manager is tightly linked to this hierarchical metadata organisation, so that in creating metadata, its organisation in series, datasets and tiles is compulsory. Therefore, it is not possible to create a single dataset without the related series. This is clearly out of the ISO19115 conceptual model. A new metadata manager is therefore under analysis. The new metadata manager should allow a flexible metadata organisation, and should work on a different metadata database conceptual model, according to INSPIRE and ISO19115. It should allow to catalogue metadata with all the values of the ISO19115 ‘MD_ScopeCode’ list. Currently, the SITR-IDT metadata manager can be accessed (both in consultation and in editing modality) only from the local SITR-IDT intranet. However, it might be helpful to extend this access in client-server mode to other Sardinian Public Administrations producing geographic data and provide these to the SITR-IDT database. It is nowadays well recognised that the most effective way to produce good quality metadata is to create it contemporarily to data production. This would be possible with a tool which allows any geographic data author, external to the SITR-IDT intranet, to access metadata manager and to create the metadata in parallel to data creation. After the data author has completed the metadata entry, the SITR-IDT metadata administrator should consult and validate the metadata. The implementation of this scenario implies to create different profiles for all the users of the metadata manager. The set up of different profiles for metadata consultation, editing, validation, publication, creation or elimination would then be necessary. The possibility of creating metadata by several users implies that precise guidelines must be made available for all metadata creators. SITR-IDT will write down and publish among all the Regional institutional producers of geographic data, appropriate operational guidelines illustrating practical case-studies covering the largest range of data that are likely to be created at a regional level. The new metadata manager should be able to export the .xml metadata files of different metadata sets, customisable depending on specific requirements (e.g. metadata set of the ISO19115 ‘Core’, of the RNDT, or others). The capability of connecting to different spatial databases (Oracle, PostgreSQL, HSQLDB) is being evaluated. Also compilation wizards could be implemented. This would allow the pre-compilation of some fields as the geographic bounding box for a shapefile, or as the distribution format for different typologies of file. A functionality for the versioning management of a metadata set should be also implemented. Finally the metadata manager should be so flexible to allow the implementation of all possible variations of national or international guidelines. 158
6. CONCLUSIONS The Public Administration of Sardinia Region is making a great effort in terms of human and economic resources to create its Spatial Data Infrastructure (SITR-IDT). In the management of SITR-IDT, great importance is given to metadata. They are object of study concerning their creation, collection and management but also for more general questions such as the individuation of the most suitable database structure and of their appropriate organisation. A good basis consisting of the individuation of the metadata structure compliant to ISO19115 standard and to INSPIRE IR has already been created in SITR-IDT. Feeding metadata to the National Register of Spatial Data will be possible without significant changes to the metadata structure adopted in SITR-IDT. However, many further steps are still to be performed in SITR-IDT to develop the metadata database and to create the tools that allow for managing metadata of different typologies of geographic data in the most appropriate way, cataloguing the information at the most appropriate level of detail and allowing metadata management by different geographic data producers.
