2 MY ONTOLOGY
Together we create your data model.
A SEMANTIC APPROACH
For the long-term preservation of your research data, together we develop specialized data models called ontologies. They are as RDF–graphs  part of the Semantic Web environment, and contain formalisms based on First Order Logic and Set Theory. In case of an existing database, we map its model to RDF. Without a database we can model directly in RDF.
 The Resource Description Framework ( combined with the RDF Schema ) and the Web Ontology Language (OWL) are data modelling languages of the W3C (World Wide Web Consortium).
In a first step the conceptual needs for data modeling are discussed and established. We create the ontologies or vocabularies based on your domain knowledge. In this process we take into account existing ontologies and terminology standards e.g. GND , Geonames, and ISO  standards, e.g. ISO 639 for languages.

GENERIC AND PROJECT-SPECIFIC MODELLING
We create the ontologies as far as possible in a generic, i.e. project-independent manner. This way we can avoid double work and reach maximal consensus on model semantics.
OPEN DEVELOPMENT ON GITHUB
We publish the ontologies together with graphics of basic semantics on the NIE-INE GitHub website. The classes and properties can be visualized in the admin frontend SALSAH 2.0. Also small ontological changes, e.g. renaming and commenting of classes and properties, can be performed here. Bigger and structural changes are discussed together and we will implement them. Furthermore you can attribute rights and annotate images stored on the Sipi server.
Data modeling is a highly iterative process. In this way RDF data can be stepwise expressed using ontologies, and stored in a triple store.
