Teaching material on Metadata for the Documentation and Archival Training Workshop Guwahati, Assam, India

Abstract

In this paper, we describe the core pillars of a large archive oflanguage material recorded worldwide partly about languages that are highly endangered. The bases for the documentation of these languages are audio/video recordings which are then annotated at several linguistic layers. The digital age completely changed the requirements of long-term preservation and it is discussed how the archive met these new challenges. An extensive solution for data replication has been worked out to guarantee bit-stream preservation. Due to an immediate conversion of the incoming data to standards -based formats and checks at upload time lifecycle management of all 50 Terabyte of data is widely simplified. A suitable metadata framework not only allowing users to describe and discover resources, but also allowing them to organize their resources is enabling the management of this amount of resources very efficiently. Finally, it is the Language Archiving Technology software suite which allows users to create, manipulate, access and enrich all archived resources given that they have access permissions.

Abstract

In many areas of the world, language archives are being created, containing information on endangered languages, adhering to sophisticated metadata schemes and archiving standards. The data deposited in these archives, however, is as of yet hard to access, especially for community members who might be easily frustrated when trying to access data. In the DoBeS archive, there are various ways of searching and browsing through the deposited data, allowing for sophisticated queries targeting information in the metadata or annotations, so that expert users can work with the language documentations. However, this user-interface is too complex for a visitor that has not been thoroughly introduced to the structures and it is difficult to find results that may satisfy typical community members’ interests. As a shortcut for users from the community, a community portal has been created which displays an array of traditionally relevant topics in a simple and attractive way and links to resources in the archive. Topics include traditional and personal stories, procedurals and traditional activities. It is suitable for school use and due to its topical structure, may also serve as a base for developing teaching materials. In the community portal, a number of pre-defined searches have been set up for certain resource categories. These categories are marked in the metadata, so whenever a metadata file is uploaded into the archive containing one of these values, it will automatically become part of the search results in the portal. The query to the metadata database is made possible through a so-called REST interface. Via this protocol, the metadata search can be accessed as a web service within any other dynamic web content management framework. This search technology could also be used to implement a portal for a broader audience, introducing the archive from various angles to different potential user groups. Here too, the dynamic searches guarantee a low maintenance effort once the portal has been created. And finally, we will show additional ways to represent archived data (e. g. using Google Earth layers), in order to draw a comprehensive picture of the various ways to enter the DoBeS archive and efficiently access relevant information. It is hoped that this paper will contribute to bridging the gap between the creation of comprehensive language documentation and community efforts at revitalization, and help researchers to fulfill their ethical commitment to make data as accessible as possible.
