Overview of this website

This website is a demonstration of a working PERC 7 instance. PERC stands for Platform for Education and Research Collaboration, and has been developed using funding from the University of Houston's biotechnology program. PERC is based on the Drupal Content Management System and PERC 7 in particular is based on Drupal version 7. PERC 7 is designed as an Electronic Lab Notebook for use in educational and research settings.

This PERC 7 instance demonstrates the use of a spreadsheet as the basis of an ELN, and how the data from that spreadsheet can be exported as RDF values to a SPARQL endpoint. The values in the spreadsheet are based on an experiment in the UH BTEC lab where the students were tasked with finding the optimal conditions for growth of E.coli. Installation of the sheetnode_rdf extension module allows the data from the spreadsheet to be exported as RDF data to the SPARQL endpoint. A mapping file is needed to delineate how the values from the spreadsheet will be exported into the RDF store. In this case the mapping file used the Minimal Description of an EXperiment, or mdex vocabulary. The RDF output from the spreadsheet can be queried from the SPARQL endpoint for this website. The default query for the SPARQL endpoint can be used to see all the data in the endpoint if the LIMIT 10 is modified to a LIMIT 100 value.
