Assessment

0. Repository Context

Applicant Entry

Self-assessment statement:

RU-IIEc (Repositorio Universitario - Instituto de Investigaciones Económicas) aims at managing, dissemintaing and preserving the intellectual production of the Economic Research Institute. This repository hosts different kinds of academic materials, ranging from books, book chapters and formal articles to radio and TV programs, mostly focused on the Economical Sciences, but also on different topics where our academic personnel is involved.


The general description of the repository can be found at http://ru.iiec.unam.mx/information.html and its usage policies are at http://ru.iiec.unam.mx/policies.html; as mentioned at the beginning of this assessment, all information is in Spanish (as it is the predominant language for the works here presented).


The repository is not outsourced in any way; it is completely hosted in our facilities and hardware in Universidad Nacional Autónoma de México, and managed by technicians working full-time for IIEc.

1. The data producer deposits the data in a data repository with sufficient information for others to assess the quality of the data, and compliance with disciplinary and ethical norms.

Minimum Required Statement of Compliance:

Applicant Entry

Statement of Compliance:
4. Implemented: This guideline has been fully implemented for the needs of our repository.
Self-assessment statement:

The repository is open for the academic works of our personnel; being a small community, they are all recognized by their names. Many external work coauthors are mentioned as authors and have objects registered to their names, but only when this is a work done together with IIEc-UNAM academicians.


All submitted works are reviewed by an academic comission formed by six people from different areas in the Institute, avoiding misrepresentations or copyright violations.


The data passed on to data consumers depends on the object — as an example, the Institute's radio program has been digitized and made available since its beginning in 1991 and part of the presentation/closing of each program include acknowledgements for the IIEc; full books carry the Institute's seal and information on them; academic articles include the academic affiliation of the authors. Some less formal objects, however, are not explicit to the consumer in this regard.

4. Implemented: This guideline has been fully implemented for the needs of our repository.
Self-assessment statement:

We don't publish a list of preferred formats, as our depositants/users are usually not very tech-savvy.


We do check (and correct if needed) data to be in a widely-usable format, and –in the case of videos– not to be in a codec producing overly long files that would hamper both our archival and interested people's downoads; we have in our policies:


The object type description is indicative, not exhaustive, and includes  materials for which the first publciation was digital. RU-Económicas resevers the right to manipulate the files, adopting the needed technical measures for them to remain always accessible.

4. Implemented: This guideline has been fully implemented for the needs of our repository.
Self-assessment statement:

Objects are only made public in the repository after the relevant metadata has been captured; most fields are filled in by the user filling EPrints' standard questionnaire. The repository's academic committee, consisting of six people, check the uploaded files before they are made public.


As a means of guidance, we do provide a object depositing manual, linked from the menu present in basically all of the repository's pages.


As the repository is structured on an EPrints software installation, all metadata is DublinCore-compliant, and available via the OAI-PMH protocol.

Self-assessment statement:

The About this repository page mentions:



RU-Económicas is the universitary repository for the Economics Resarch Institute (IIEc) at UNAM, created to manage, disseminate and preserve, in digital format, the intellectual production of the Economics Research Institute.


This repository's mission is to stimulate academic communication and increase visibility and utilization for contents produced in the Institute. It hosts diverse materials, which can (or not) have been peer-reviewed, such as books, magazines, articles, presentations, databases, audiovisual material, etcetera.


RU-Económicas provides the public in general, students, teachers and researchers, a search and acquisition service for the digital resources produced by the academic community of the Economics Research Institute.



We have had courses and talks on how to deposit material with our academic personnel.

4. Implemented: This guideline has been fully implemented for the needs of our repository.
Self-assessment statement:

The repository itself is not a legal entity, but it is managed by a committee of six academics inside a research institute.


We have two standard forms for people uploading works, one for academics in our university and a different one for authors not affiliated to UNAM. We do not have any kind of contracts for data consumers.


Legal rights are outlined both as a footer for every generated page and delineated in the policies page. If conditions are not complied with, the policies page mentions that i.e. if the repository has knowledge of copyright violations in the deposited objects, they will be immediately removed; we decided to take a reactive approach in order not to hamper the ease of depositing with express contrat signatures.


All of the documents uploaded to the repository are meant to be publicly accessed, so we do not set disclosure risk or access limitations; the system administrator is well versed in computer security, so the risk for accounts leakage is small; the software is kept up to date with the upstream versions.

Self-assessment statement:

The repository is expressly built for preservation, although it does not have per se a preservation policy (besides the already mentioned reserve we have to manipulate objects so they are always accessible, which could include format conversions). We do have a backup: Every two days, a full filesystem backup is done to a semi-offsite computer (that is, not off-campus, but ~50m away from the production server). Backups are done first as a regular MySQL database dump to stable files, and then via rsync. Backups are kept for two weeks. No long-term backup is made.


Storage media deterioration is prevented by having all data (both on the server and on the backup system) stored in RAID-mirrored volumes; server logs are monitored on a daily basis for I/O warnings.

Self-assessment statement:

Although it is not a concrete provision, being able to convert files to a different format is one of our site's policies. So far, I have only had to recode videos (as they were uploaded in DVD format, which yields a very bad compression rate and are not fit for Internet-delivered content).

Self-assessment statement:

There are some divisions in our research institute in which the personnel uploads all produced material, such as the radio program, magazines and non-periodical editorial bodies. For all other academics, we require and encourage self-deposit.


Those three areas do have the repository as part of their content-producing workflow.


We have had presentations with the academic groups showing them how to use the repository, and have prepared a short depositing manual to help with the depositing workflow.

4. Implemented: This guideline has been fully implemented for the needs of our repository.
Self-assessment statement:

Our policies page states:



  • Any member of IIEc can request contents to be deposited in this repository

  • The depositor will be responsible for the work's content, integrity and pertinence.


As it is restricted to authors being part of our academic community (full-time university employees), our juridic area said we didn't need any further contracts or licenses to be granted, the works belong to the university.


As for crisis management, we have backup retrieval procedures.


Our repository server is backed up in a separate computer (same building, but a separate place) at a database and filesystem level three times a week, and backups are retained for a one month period; in case of data loss or corruption, files and database structures can be restored within a day or two to a fully functioning new server.

Self-assessment statement:

Close to half of our objects are MP3 files (from the site's statistics), which are naturally not deep-searchable, but the rest is, we have in fact a collaboration pending to be integrated that uses precisely that properties.


The site does offer basic and advanced search facilities and OAI-PMH harvesting.


We do not currently use DOI or the Handle system, as it has so far been outside the needs of our academic community; we are committed to long-time stability of our repository objects' public URLs, but do not use a third party service for this.

3. In progress: We are in the implementation phase.

Statement of Compliance:
4. Implemented: This guideline has been fully implemented for the needs of our repository.
Self-assessment statement:

The repository is built using EPrints, which takes care of versioning; it is not publicly viewable, but every object has a full modifications log.


We are not using checksums for data integrity.


As the system administrator (and with some due experience in data security handling), I do not believe the mere fact of storing checksums in a high-level construct such as the database backing our files would mean much as to detecting data gone bad; checksumming is naturally done at the operating system and database levels. Checksumming is done as part of the filesystem block replication strategy (the repository is stored in a mirrored hard drive), and any discrepancies would raise alarms to a possible faulty disk.


That is, the integrity does use checksumming, but it is not done at a repository-visible level.

Self-assessment statement:

Our objects are of relatively simple nature, and do not usually change over time. We could present the object modification history (provided by EPrints) as an audit trail, but I'm not sure whether it satisfies the question.


We do not link to any external datasets.


As for the depositors' identity, we do E-mail validation only.

Self-assessment statement:

All objects are catalogued using the DublinCore fields. For thematic categorization in the Economics research community, we require objects to be classified according to the JEL (Journal of Economic Literature) hierarchy; this can be seen in our advanced search pages.


While our repository was not built based on (or with due knowledge) of OAIS, it aligns quite well with its structure and goals, and in our opinion can be seen at least as being in the "in implementation" phase. Refering, as suggested by the reviewer, to other assessments:



As for the mandatory OAIS responsabilities (section 3.1):



  1. The information is accepted from the producers by the means of the self-deposit.

  2. Enough control is obtained, as legal rights are ensured and our policy states:
    Technical validation of the deposited objects is in charge of the technical responsible of RU-Económicas, and the content's validation is responsability of the Academic Repository Commission, that has the attributions to accept, reject or remove objects according to this policy.
    (...)
    RU-Económicas reserves the right to manipulate the files as to adopt the technical measures needed for them to always remain accessible.


  3. The Academic Repository Commission has determined that any person interested in the academic works of our institute is part of the Designated Community; the sometimes technical nature of its contents mean the knowledge base will most often require studies in economics and related fields.

  4. Information is independently understandable in as much as the depositors segment it as discrete entities; most of the objects are self-contained and have been curated/reviewed by peers (in the case of published books, articles and similar objects) or conducted (in radio program transmissions); others, such as presentations and lecture notes are accepted into the repository, and they are often linked to the discourse the author builds around them, but are assumed to carry value by themselves, even if not the full value of having the author teach/present them.

  5. No users but the Academic Commission are allowed to remove an object from the archive, and the committee will not do this except in very grave cases, such as copyright infringement. The demise of the archive itself is not contemplated, but part of the integration with CCUD (mentioned before) has the explicit intention of ensuring data survival.

  6. The information is available to the Designated Community as it is publicly available on the Internet, with explicit licensing terms (already linked to in relevant sections of this assessment) allowing for use and redistribution; files are not currently watermarked to provide a proof of provenance or authenticity, but this can be looked into in the future.

Self-assessment statement:

Consumers are passive in our repository, they can only download objects. All objects in our repository are public, so there is no notion of confidential data; consumers do not have to identify themselves. Data consumers basically just agree to using the downloaded information in accordance to our licensing terms, which are broadly speaking similar to a CC BY-NC-ND license.


Producers do share some more data of them as human subjects: At least, depositors' e-mail address, which is always validated (and kept private to the system administrator), as well as –of course– names for the authors of every available digital object. If a given person demands not to be associated with a given work of their authorship, that work is removed from the repository.
