A linked-data vocabulary of grey literature document types: Version 1.0

Petra Pejšová


The role of grey literature in today society was well expressed by Vaska: “It is therefore remarkable how efforts over the past two decades have altered originally preconceived notions of grey literature, resulting in a deeper understanding of how the formation, retrieval, and use of non-traditional material becomes a fundamental companion in one’s research endeavors. The advent and use of new technologies, a prevalent trend in 21st century society, has created increasing awareness of the need to incorporate the grey alongside the white, a boundary that is becoming less distinct and which may become translucent in the not-too-distant future.”(Vaska, 2010) The poster presents the first version of the vocabulary of the types of grey literature in RDF (Resource Description Framework), which is based on an analysis of grey literature typologies and a draft version of vocabulary presented on 12th International Conference on Grey Literature. The draft version of the vocabulary of the types of grey literature was reviewed by 14-member international working group appointed to this purpose. For cooperation work we chose the methodology of Google Code, a free collaborative development environment for open source projects, available at http://code.google.com/p/grey-literature-typology/. Vocabulary of the types of grey literature is a hierarchically structured typology and is distributed as a controlled vocabulary in machine-readable format. The vocabulary is exposed in RDF/XML and Turtle. Both of the formats are available on project website:
1. RDF/XML (http://code.google.com/p/grey-literature-typology/source/browse/gltype.rdf)
2. Turtle (http://code.google.com/p/grey-literature-typology/source/browse/gltype.ttl).
