Authorship: the publication of documents in the DDD involves the transfer of the right of public communication to the UAB in a non-exclusive nature, which means that the owners of the rights keep those rights.
Copyright: DDD documents are subject to copyright and, therefore, their use is regulated by the current Intellectual Property Law.
Each record has a mention of rights that regulates the use of each document. Licences used are Creative Commons licenses, public domain or all rights reserved. See Recommended Creative Commons Licenses at the UAB.
Use of personal data: in accordance with the adaptation of the Organic Law of Protection of Personal Data 15/1999, the DDD in no case discloses the information of its users regarding deliveries or individual visits to the repository nor the Email address required to register if you are not a member of the university community.
We follow the General Regulation of Data Protection (RGPD) to protect data and privacy. DDD only collects email addresses of users that do not belong to the university community; in no case the Library Service staff can view personal passwords.
Users that have not accessed their personal accounts in the previous 5 years will be discharged unless they have pending baskets.
Language: There are interfaces in Catalan, Spanish and English. Documents are collected in any language and alphabet.
Permanent link: All DDD documents are assigned a permanent link that can be seen in the record.
Versions: different versions of a document are maintained.
File format: the deposit accepts all types of formats, but it is advised to use open formats to make reuse easier; for example, pdf for textual documents.
File name: It is essential to properly name the files of the records in order to manage electronic resources effectively. To name the files we recommend:
- Choose names that are sufficiently descriptive of the content, for example, using part of the bibliography record of the document.
- Do not exceed 25 characters.
- Avoid naming them by a number, as it is not descriptive enough of the record context.
- Avoid using characters such as ,. :; / () $ & |  * <> "¿?
- Use the underscore (_) rather than blank spaces between words.
- For records that have different versions, it is advisable to differentiate them by indicating v01, v02, etc., instead of update, new, etc. As an exception the final version could be called FINAL. In these cases, it is advised to be consistent when naming the different files in order to keep internal coherence.
Volume and size limits for files: it is recommended that files do not exceed 200 pages and / or 200 MB. The datasets cannot exceed 25 GB.
In order to register, fill out the following form. If you are a member of the UAB university community, use always your NIU and password. If you are not a UAB member, use your email. The registration will be effective immediately and you will have access to various features.

Access to records metadata and its re-use are subject to a CC0 license.
National (Plan Estatal) and European (H2020) policies require that all peer-reviewed scientific publications are deposited in open access, in the case of European projects also the research data must be deposited. DDD is the UAB platform that helps researchers to fulfill these mandates.
DDD uses the Invenio software, which is an open source software under MIT license that was created at the European Council for Nuclear Research (CERN).
The hardware system has all kinds of guarantees of redundancy and reliability and is subject to the usual renewal and security protocols of the University Information Service (Servei d’Informàtica de la UAB). Backups, including those stored outside the university's facilities, follow the same circuits than the rest of the UAB's digital information.
The Open Archives Initiative model allows interoperability with the OAI-PMH metadata transmission protocol (Open Archive Initiative - Protocol for Metadata Harvesting). This protocol allows the visibility of the documents from different platforms and collectors: Google Scholar, BASE, CORE ...
In order to fulfill the European mandates, the DDD is OpenAIRE compliant ast it meets all the requirements of metadata required by the European Union, to be able to revise the projects. Persistent IDs are provided for each document and author identifiers (ORCID) are included in the metadata.
The Library Service will verify publishing rights to guarantee copyright policies for deposited documents.
The UAB Governing Council (Consell de Govern) has approved the policy for preservation of documents available in the DDD, which states the institutional sustainability of the infrastructures, as well as the distribution of the different responsibilities within the services and governing bodies of the University.
