The CRDO project (a Resource Center for the Description of Oral) was initiated in 2006 under the banner of CNRS, the National Center for Scientific Research in France. Now renamed SLDR, it is offering labs and independent scholars a free-of-charge service for the storage, sharing and long-term preservation of sound/video recordings and their related material in compliance with the OAIS model.

This site is dedicated to SLDR (identity: http://sldr.org/oai-pmh.php?verb=Identify).

Items belonging to four categories are available on the site:

• Primary data, basically oral/video corpora and any speech-related signal;
• Resources such as annotations of corpora, lexicons, reference databases, systems of representation, grammars…;
• Tools for linguistic research;
• Collections binding together several items of the defined types.

SLDR (sldr.org) is hosted by Université de Provence. Currently, packages are distributed via the TGE-Adonis grid hosted by CC-IN2P3 and preserved on the archival platform of CINES.

Sharing linguistic resources is a comprehensive response to the challenge of bringing together knowledge that has so far been scattered over such diverse domains as descriptive, formal and computational linguistics, literature, translation science, neuroscience and psycholinguistics.

Features specific to SLDR

• SLDR makes it possible to share documents as current data (on the submission site), as a medium-term archive (via the TGE-Adonis grid hosted by the development platform of CC-IN2P3) or as a long-term archive (via the TGE-Adonis grid associated with the archival platform of CINES). Procedures for accessing documents are identical in these three cases. Thus, producers may easily modify the archival status of any item in compliance with the research program from which it originates.

• All situations have been taken care of with respect to access rights:

  • Items in open access (optionally under Creative Commons licence);
  • Items in restricted access (as per user groups);
  • Items in restricted access with some file in open access;
  • Items in privileged access to some users (downloading, source files, versions, metadata editing).
• Any document (datastream) in a given item may be assigned a private/public status. Public status allows for open access (skipping user's authentication).
• The private/public status of any document in any version of an item can be modified without uploading a new version of the item.
• Additional descriptive documents (free consent forms, licences, notes…) may be added/deleted/modified without uploading a new version of the item.
• Multi-language access to data: navigation is possible in four languages (English/Spanish/French/Chinese) ; descriptions, keywords and tables of contents may be entered in an optional language in addition to navigation languages.
• SLDR is at the service of producers of speech/linguistic resources, i.e. laboratories (see current list) and individual producers irrespective of institutional/geographical boundaries. Its client-server architecture allows producer laboratories to install their own web services for the display/streaming/analysis of their data distributed via SLDR.
• The range of contributions is as wide as possible, from experimental linguistics (laboratory data) to contact linguistics (field data).
• Contributors do their best to supplement data with resources and tools that will facilitate their processing. The aim is to offer a whole set of devices, from primary acoustic signals to the editing and processing of these signals. This service should give access to information, tools and methods allowing data analysis as well as annotations produced by these tools.
• Each item may be put in relation with publications, teams and research programs.
• An item may be stored with SLDR as a personal deposit or in connection with the institution(s) which its author(s) was/were affiliated with at the time of its production. Each institution may declare a path from which its information system will be able to deal with instructions from SLDR triggering processes associated with a particular item. (See details and the list of institutions).
• Downloadings invoking the SLDR non-commercial licence are traced and followed up. Users commit themselves (1) to mention their use of downloaded items in every publication and (2) to enter on the SLDR website the references of publications based on this use. In this way, the relevance and utility of each corpus, tool or resource distributed by SLDR may be assessed by the speech research community.
• Users of any item distributed by SLDR are granted access to the names, professional affiliation and fields of interest of all users who downloaded the same item. This feature is complementary to the sharing of publications. Its aim is to promote the emergence of communities of producers and users (Web 2.0 approach) collaborating on research projects making an optimal use of available resources.

SldrWiki

This wiki space is dedicated to the production and sharing of information about:

• projects related to corpora, tools and resources distributed or documented by SLDR;
• teams working on these projects;
• scholars taking part in these teams;
• documentation on corpora, tools and resources distributed by SLDR — direct links may be retrieved from records stored on the SLDR site.
