Dear Semantic Web group members

I have created a questionnaire to help understand how people are using SPARQL. As many of you will know, there have been a number of analysis of SPARQL query logs, which offer some insight into the nature of queries but little insight into the requirements and thought processes of those initiating the queries. This questionnaire attempts to get a better insight into how SPARQL is being used and what difficulties are being experienced. The questionnaire, which takes around 20 minutes, is available at: https://openuniversity.onlinesurveys.ac.uk/sparql-survey All responses to this survey are extremely valued. The results will be made available in the public domain and this group will be notified. The closing date for the questionnaire is 14th April.

Many thanks Paul Warren, Knowledge Media Institute, Open University, U.K.
