XML and semantic data formats (RDF) are currently in the main focus of many researchers
who propose and develop more and more efficient techniques for their processing.
Consequently, being users, we need to know which of the existing approaches is the most
sufficient for our particular application. On the other hand, being vendors who develop
a new SW or researchers proposing a new approach, we need to test its correctness and
 performance and, especially, to compare its main advantages with competing
representatives. And being analysts, we are especially interested in comparison of
various aspects of existing systems and methods from different points of view.
Consequently, standardized approaches to testing the developed techniques and their
mutual comparing need to be proposed and developed as well.

It is very common, however, that suitable testing data are not easily available and,
hence, they need to be synthesized. Therefore, not only predefined fixed XML and
semantic data sets but also methods for their synthesis on the basis of user-specified
constraints are essential. They can involve physical parameters such as size, depth,
fan-out etc. as well as more complex ones such as integrity constraints.

Another problem related to XML and semantic data processing is that the techniques
often require a kind of structural or semantic description of the processed data,
such as XML schema or ontology. However, in real-world situations the schema is often
missing or, if it exists, the data are not fully valid. Hence, the techniques must be
accompanied with methods for inferring schemas as well as integrity constraints.

And, finally, a true benchmark involves not only data, but also respective operations,
such as queries, XSL transformations etc. Therefore another set of open problems
related to specification of reasonable benchmarking operations opens.

We invite submission from research communities dealing with different theoretical
and applied aspects of XML and semantic data benchmarking. The papers can cover
 results and experiences with benchmarking selected applications, proposals of
benchmarking projects, approaches to synthesis of data sets and/or operations,
as well as other related topics such as analyses of real-world data collections, schema
inference, integrity constraints inference etc.

Areas of interests include, but are not limited to:

• XML benchmarking projects
• Synthesis of XML data
• Inference of XML schemas
• Inference of XML integrity constraints
• Analysis of real-world XML data, schemas and queries
• Analysis and/or performance comparison of XML-related applications (parsers, validators, XML managements systems, query engines, XSLT processors, XML archivers, ...)
• Semantic web benchmarking projects
• Synthesis of semantic web data (RDF, OWL, ...)
• Ontology inference
• Analysis of real-world semantic web data, ontologies and queries
• Analysis and/or performance comparison of semantic web-related applications (reasoners, semantic data management systems, mappers, query engines, ...)
• Benchmarking and testing of (semantic) web services
