+* on your website:
+ * include the DBpedia logo and mention the usage of DBpedia with this link: https://databus.dbpedia.org/dbpedia

+
+
+## How to contribute
+DBpedia is a community project, help us with this dataset:
+* improve this documentation at https://github.com/dbpedia/databus-maven-plugin/tree/master/dbpedia/mappings/${project.artifactId}/${project.artifactId}.md
+
+## Origin
+This dataset was extracted using the wikipedia-dumps available on https://dumps.wikimedia.org/
+using the DBpedia Extraction-Framework available at https://github.com/dbpedia/extraction-framework
+For more technical information on how these datasets were generated, please visit http://dev.dbpedia.org
+
+## Issues
+* documentation is too unspecific, the text extraction needs a more detailed description and better links
+* there seems to be invalid characters in the dataid file, however, the loading and rdf parsing work fine
+
+# Changelog
+## 2016.10.01
+* old dataset from 2016
+* quite old, but work on new releases is on it's way
+* mimetype is detected by a parse over the 10-line preview, line by line. If no wrong triples are found, we assume that it is ntriples, which is a subset of turtle, however, this fails here, sometimes.
+* normalisation of langs: zh_yue to yue, zh_min_nan to nan, bat_smg to batsmg
+* we used rapper 2.0.14 to parse and `LC_ALL=C sort` to sort and ascii2uni -a U to unescape unicdoe
+characters
+* link to Wikimedia dump version is missing

+# Wikidata Alias
+Wikidata-specific dataset containing aliases for languages in the mappings wiki. Aliases for languages not in the mapping wiki are found in the _nmw variant.
+
+Aliases are alternative names for items that are placed in the Also known as column of the table on top of every Wikidata item page.
+From https://www.wikidata.org/wiki/Help:Aliases
+There can be several aliases for each item, but only one label (other dataset).
+
+## Issues
+Currently data is grouped in two categories:
+* aliases from mapping wiki languages (around 40)
+* aliases from all other languages
+In the future, we might separate these into one file per language, which will increase the number of files from 2 (nmw as content variant) now, to many (basically using iso codes as content variants, beyond the 120 wikipedia versions)
+This is under discussion however.

+# Wikidata Instance Types
+Contains triples of the form $object rdf:type $class

+Using P31 as rdf:type .
+If the typed class is in in the DBpedia Ontology, it will be used, otherwise the type is discarded.
+E.g.
+
+```
+<QXYZ> <P31> <Q5> . # Q5 is Person
+<Q5> owl:equivalentClass dbo:Person .
+------------------------
+<QXYZ> rdf:type dbo:Person .
+```
+Function used:
+```
+ "P31": [

+],
+
+```
+
+The extractor uses the data from ontology-subclass-of artifact to optimize the hierarchy and enrich equivalent classes.
+
+The mappings between Wikidata Items and classes can be edited in the [Mappings Wiki](http://mappings.dbpedia.org/index.php/OntologyClass:Person)

+## Origin
+This dataset was extracted using the XML wikidata-dumps available on https://www.wikidata.org/wiki/Wikidata:Database_download
+The extraction is performed using the DBpedia Extraction-Framework available at https://github.com/dbpedia/extraction-framework
+You may find more details on the Wikidata extractions at "Wikidata through the eyes of DBpedia" by Ali Ismayilov, Dimitris Kontokostas, Sören Auer, Jens Lehmann and Sebastian Hellmann.
+You may download the article from http://www.semantic-web-journal.net/content/wikidata-through-eyes-dbpedia-1
+
+## How to contribute
+DBpedia is a community project, help us with this dataset:
+* Extend and/or improve the Wikidata class & ontology mappings at the DBpedia mappings wiki (http://mappings.dbpedia.org)
+* Extend and/or improve the Wikidata json mappings at https://github.com/dbpedia/extraction-framework/blob/master/core/src/main/resources/wikidatar2r.json
+* Improve this documentation in the pom.xml at https://github.com/dbpedia/databus-maven-plugin/tree/master/dbpedia/wikidata/pom.xml
+* Improve the software at: https://github.com/dbpedia/extraction-framework
+
+## Known Issues
+* RDF parsing and sorting failed for artifacts rediects, references, raw and sameas*
+* we are attempting to switch from rapper to Sansa-Stack: http://sansa-stack.net/sansa-parser-performance-improved/
+
+## Group Changelog
+### 2018.07.20 to 2018.11.30
+* were created as new modular releases, some issues remain
+* removed wikidata-sameas
+* removed raw for now
+* mappingbased objects are not cleaned
+* we used rapper 2.0.14 to parse and `LC_ALL=C sort` to sort and ascii2uni -a U to unescape unicdoe
+characters
+* link to Wikimedia dump version is missing
+## 2018.10.01
+* deleted due to bzip2 non-recoverable bad blocks

+# Wikidata properties with labels
+Wikidata property URIs as subject and dbo:alias to their labels
+
+A dump of all Wikidata properties. Some of them were used to generate mappings in R2R, e.g.
+```
+<http://www.wikidata.org/entity/P957> <http://www.wikidata.org/entity/P1630> <https://www.wikidata.org/wiki/Special:BookSources/$1> .
+```
+
+## Issue
+* The R2R mapping derived from this dataset, would need to be updated, but the update is manual atm, automation possible
