Repository Management
The Repository Management menu provides functionalities that help you manage your repository: it is possible to clear the repository, to export it into an rdf file and to load an external rdf file that will be added to your working ontology (so it differentiates from a traditional import which is readonly). The last option opens the Ontology Mirror Management window, which is descrisbed here below
Export Repository
If you choose Export Repository, the window below will be opened, prompting you for the directory where you want to export your ontological repository and for the name of the saved file. You can use any extension for your file (but we recommend rdf or owl extension, which are normally associated to rdf content).
Load Rdf
If you have a valid rdf file, you can load it into Semantic Turkey using Load Rdf option in Repository Management menu. Through the Load Repository window you can browse your file system to select the file to be loaded, and specify its baseuri. Note that the file content will be loaded inside your working ontology, so you will be able to modify it. This is the main difference with respect to the import options on the Import Panel which allow to reuse existing ontologies by importing their content in read-only. This option is typically used to reimport data which has been previously backed up from your old repository, or to exchange ontologies with other people.
Clear Repository
Through this action, the ontology repository will be completely cleared.
Pay attention to this action because it erases all information in your repository (we recommend to export the existing repository before clearing it).
After cleaning the repository, Semantic Turkey restarts Mozilla Firefox, and will again prompt you with the first start panel
Manage Ontology Mirror
By choosing Manage Ontology Mirror, the Ontology Mirror Management will be shown. This window shows the complete list of ontologies which are mirrored in your computer. The mirrored ontologies appear as <baseuri, mirrored file> pairs. You can delete an ontology from the mirror (in this case, if that ontology is imported in your working ontology, Semantic Turkey will try to import it from the web the next time it is started), or update its content (in case it has been modified after you mirrored it). If you choose to update, you have three options
- update from Web (using baseuri as location): Semantic Turkey tries to retrieve a new version of the ontology by downloading it from an URL equivalent to its baseuri
- update from Web (from alternative URL): the ontology is downloaded from an alternative URL which the user is prompted for
- update from Local File: the ontology is updated with the content taken from a local file in your machine
