Quelltext der Seite Technical Description Use Case VFU-ELF

Semantic CorA was developed in close connection to the use case of analyzing educational lexica in research on the history of education. In this context, two researchers are working on their doctoral theses in the vre.

=Research Data=
In both research projects the examined data were educational lexica. A lexicon can be subdivided into three more entities: a volume, an article (lemma) and the image file of the digitalization. Each entity has its own properties (see image "Entities for Lexica") . On this basis, we created a data model which made it possible to describe the given data. [[File:entities_CorA.png|right|thumb|400px|Entities for Lexica]]
==Import and Handling==
We were able to import bibliographic metadata (describing the data down to the article level) and the digitized objects from [http://bbf.dipf.de/digitale-bbf/scripta-paedagogica-online/digitalisierte-nachschlagewerke Scripta Paedagogica Online (SPO)] which was accessible via an OAI-Interface; in an automated process, nearly 22,000 articles from different lexica were imported that were described with the data model and were ready for analysis. To add more articles manually, we developed the extension [[Semantic_CorA_Extensions#OfflineImportLexicon OfflineImportLexicon]] which provided a standardized import routine for the researchers.

==Data Templates of Lexica==
The usage of templates offers a centralised data management. Using these feature, a baseline for the data import and display is provided. Following the described entities of a lexicon, each level of entity contains several data. 

The [[Template:Cora_Lexicon_Data|Cora Lexicon Data]] template is called through the following format:

<pre>
{{Cora Lexicon Data
| Title =
| Subtitle = 
| Place of Publication  =
| Editor = 
| Coordinator =
| Author = 
| Publisher = 
| Language = 
| Edition =
| URN =  
| Year of Publication =  
| IDBBF =  
| Has Volume = 
}}
</pre>

The [[Template:Cora_Volume_Data|Cora Volume Data]] template is called through the following format:

<pre>
{{Cora Volume Data
| Title =
| Subtitle = 
| Volume Number =
| Place of Publication  = 
| Publisher = 
| Editor =
| Language = 
| URN =  
| Year of Publication =  
| IDBBF =  
| Physical Description =  
| Part of Lexicon = 
| Numbering Offset = 
| Type of Numbering = 
}}
</pre>




The [[Template:Cora_Lemmata_Data|Cora Lemmata Data]] template is called through the following format:
<pre>
{{Cora Lemmata Data
| Title =

| Part of Lexicon = 
| Part of Volume = 
| Language = 
| URN =  
| IDBBF = 
| Original Person =
| First Page =  
| Last Page =  
| Has Digital Image =
| Category = 
}}
</pre>


The [[Template:Cora_Image_Data|Cora Image Data]] template is called through the following format:

<pre>
{{Cora Image Data
| Original URI =  
| Rights Holder =  
| URN = 
| Page Number = 
| Page Numbering = 
| Part of Article =  
| Part of TitlePage =
| Part of TOC =
