Converting EAD to XSLT using XSLT and Saxon<\/strong><\/p>\n We use the Saxon<\/a> HE XSLT (Java) version to the do transformation. It’s simple to download and setup. The basic core step is very simple: run Saxon, passing it the name of the EAD\/XML file and the XSLT file. An example command line looks like this:<\/p>\n And there you have it, your EAD data is now RDF!<\/p>\n Before the data is loaded in to the Talis Platform store, there’s a couple more things we do.<\/p>\n Triples and Turtle<\/strong><\/p>\n The first is the conversion of the RDF\/XML in to the alternative RDF format\u00a0N-Triples<\/a> (and also Turtle<\/a>) using the Raptor RDF parser.<\/p>\n RDF can be written and presented in a number of ways. Probably the most common method is using XML, partly due to the XML language<\/a> being\u00a0so\u00a0ubiquitous, however it is very verbose and can be difficult to read by us humans.<\/p>\n Not only is N-Triples considered easier to read. but each line contains a fully complete and self-contained Triple (a Triple contains a subject, predicate and object, mostly expressed as URIs). While it isn’t too much of an issue here, this allows us to split up the data in to smaller chunks\/files which can be POSTED to the Talis Platform.<\/p>\n Talis Platform<\/strong><\/p>\n The Talis Platform is a well established Triple Store (think of a SQL database but with three part triples rather than records and tables). While you can run your own Triple Store using software such as ARC2, the Talis Platform provides a stable, robust and quick solution.<\/p>\n You interact with the Platform with standard HTTP Requests; GET, POST, DELETE etc. However for\u00a0simplicity\u00a0an\u00a0interactive\u00a0command prompt front end has been developed in Python called Pynappl<\/a>. This allows you to simply specify the store you wish to work with, authenticate, and then use commands such as ‘store filename.rdf’ to upload data.<\/p>\n A simple script can upload our data to the Platform, uploading each n-triple file created above.<\/p>\n The final step is to try our the Sparql <\/strong>interface at:<\/p>\n http:\/\/api.talis.com\/stores\/massobservation\/services\/sparql<\/a><\/p>\n Here’s one to try:<\/p>\n To take our EAD from Calm and turn it in to Linked Data we used a XSLT script written by Pete Johnston, used Saxon to transform the EAD\/XML in to RDF\/XML using the XSLT script. Then we converted the RDF\/XML to RDF\/N-Triples using Raptor. And finally we used Pynappl to upload this to the Talis Platform.<\/p>\n The XSLT scripts mentioned here can be found at:<\/p>\n http:\/\/data.lib.sussex.ac.uk\/files\/massobservation\/xslt\/<\/a><\/p>\n The RDF Linked Data is available for download, in addition to the SPARQL interface above:<\/p>\n http:\/\/data.lib.sussex.ac.uk\/files\/massobservation\/rdf\/<\/a><\/p>\n My Thanks to Pete Johnston of Eduserv for providing the process (with documentation) described above.<\/em><\/p>\n This page has been translated into Spanish<\/a> by Maria Ramos from http:\/\/www.webhostinghub.com\/support\/edu<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" In my last blog post I discussed how to setup our server to handle the URIs being created within our Linked Data, and said the next step was for us to turn our EAD\/XML data from Calm in to RDF\/XML Linked Data.
