 \subsection*{Infrastructure Components}
-There are multiple relevant activities being carried out in the context of research infrastructure initiatives for LRT. The most relevant ongoing effort is the \texttt{VLO - Virtual Language Observatory}\footnote{\url{http://www.clarin.eu/vlo/}}\cite{VanUytvanck2010}, being developed within the CLARIN project. This application operates on roughly the same collection of data as is discussed in this work, however it employs a faceted search, mapping manually the appropriate metadata fields from the different schemas to 8 fixed facets. Although this is a very reductionist approach it is certainly a great starting point offering a core set of categories together with an initial set of category mappings.
+In recent years, multiple large-scale initiatives have been set out to combat the fragmented nature of the language resources landscape in general and the metadata interoperability problems in particular. A comprehensive architecture for harmonized handling of metadata -- the Component Metadata Infrastructure (CMDI)\footnote{\url{http://www.clarin.eu/cmdi}} \cite{Broeder+2011} -- is being implemented within the CLARIN project\footnote{\url{http://clarin.eu}}. This service-oriented architecture consisting of a number of interacting software modules allows metadata creation and provision based on a flexible meta model, the \emph{Component Metadata Framework}, that facilitates creation of customized metadata schemas -- acknowledging that no one metadata schema can cover the large variety of language resources and usage scenarios -- however at the same time equipped with well-defined methods to ground their semantic interpretation in a community-wide controlled vocabulary -- the data category registry \cite{Kemps-Snijders+2009,Broeder+2010}.
 
-\texttt{Component Registry} and \texttt{ISOcat}\footnote{\url{http://www.isocat.org/}}
-are two integral components of the \textit{CLARIN Metadata Infrastructure} maintaining the normative information. Especially \texttt{ISOcat} -- the ISO-standardized Data Category Registry for registering and maintaining \texttt{Data Categories} as globally agreed upon incarnations of concepts in the domain of discourse -- is the definitive primary reference vocabulary \cite{Broeder2010,ISO12620:2009}. A tightly related work is that on the so called \texttt{Relation Registry}, a separate component that allows to define arbitrary relations between data categories, however this activity is rather in an early prototypical phase.
+Individual components of this infrastructure will be described in more detail in the section \ref{components}.
 
-And a last relevant intiative to mention is that of a \texttt{Vocabulary Alignment Service} being developed and run within the Dutch program CATCH\footnote{\textit{Continuous Access To Cultural Heritage} - \url{http://www.catchplus.nl/en/}}, which serves as a neutral manager and provider of controlled vocabularies. There are plans to reuse or enhance this service for the needs of the CLARIN project.

-\noindent
-All these components are running services, that this work shall directly build upon.
