COCOON supports producers of oral resources, to create, structure, share and archive their corpora. This support covers advice upstream of a project, assistance in modeling and formatting resources, up to management services for stored data (secure storage, enrichment of descriptions, sharing, referencing, archiving).
- Cocoon members can be called upon to provide advice prior to a collection project. How to digitize old media? What format and encoding should be chosen for new recordings? How to define a naming conventions and a classification plan? How to secure the data as they are collected? How do you describe data lifecycle management choices in a funding application?
- When an audio or video resource is submited in Cocoon, it is checked by validation tools. If the format used is not one of those accepted by Cocoon, a conversion will be performed automatically. Broadcast files in other formats are also added to facilitate consultation on the web. The physical storage of the data is carried out on the service grid of the IR* Huma-Num.
- The resources deposited in Cocoon initially feed a "private" environment accessible only to the depositor. An administration interface allows the depositor to describe and organize his resources until he is ready to make the result of this documentation work freely accessible (access to records and annotations can be restricted for a period to be defined, if the nature of the content requires it). It is only then that the mechanisms for identification, enrichment, referencing and archiving can be implemented.
- For each resource, one or more persistant identifiers are assigned to it (an OAI identifierand a DOI initially, then, if the resource is archived, an ARK type identifier, and finally, when the resource is harvested by ISIDORE, another HANDLE type identifier). To facilitate the citation of resources, permalinks of type PURL, ARK and HANDLE can be used and a form of citation is proposed on the presentation page of each resource. In addition, to help the management of references in bibliographies, an interface (unAPI) with the Zotero software is provided on these pages, allowing those using this free software to automatically retrieve the metadata.
- When the description of a resource is made public, an alignment work on repositories is carried out in order to take advantage of the wealth of information they contain. This alignment work is carried out on people and organizations, languages, places and subjects.
- The Cocoon warehouse has an OAI interface which is used by "harvesters" with whom it is registered (for example: Isidore , OLAC , Worldcat , OpenAIRE , CLARIN , etc.).
- Cocoon also exhibits its public resources on the Linked Open Data model to facilitate their discovery by automata and their reuse.
- A copy of the resources may be entrusted to CINES (in the Archive of the IR* Huma-Num) which will ensure the permanent preservation during the interim period before transferring it eventually for final conservation to the National Archives .
