IT IS TIME FOR AN ICHNOLOGICAL DATA BASE: THEORETICAL CONSIDERATIONS, BENEFITS AND TESTING SAMPLE WITH EASYDB
To design the database, we began from the premise that it should have a flexible structure to allow modification and changes especially to ichnotaxonomy, according to new studies. This can be achieved through the structure of EasyBD: the main item, constituting the fundamental base for all the information added, is the ID of the single track – either an official museum or field label are accepted. To this object (the ID) a range of data (e.g., 3D model, photos, diagnosis/description, line drawings, measurements) can be directly linked. The ID of the single track is then connected to a series of hierarchical POOLS, based on non-modifiable information (e.g. Trackway, tracksite, locality etc.). Other features of the tracks (e.g., posture, size and preservation), their interpretation (ichnotaxonomy and trackmaker) and geological setting (e.g., group, formation, member/unit, sediment, age, palaeoenvironment and palaeogeography) are added as TAGS. Tags can be hierarchical, can be linked to different pools, and above all, can be modified after the first entry. Competing taxonomy can thus be depicted by parallel sets of trees of tags. The example provided wishes to illustrate common ichnological cases in order to create a solid background for the development and release of the data base.
