CDASH TO RDF 31 May 2013 PhUSE Emerging Technologies Semantic Technologies WG

Agenda Introductions Goals (Frederik) CDASH – An Overview (Rhonda, Gary) Source Control (Geoff)

Project Goals Model and Publish CDASH 1.1 in RDF Scoping: –What needs to be included into the CDASH RDF Model? – Other models: (Ex: BRIDG)

CDASH – AN OVERVIEW

SOURCE CONTROL Source control gives you security –Ability to rewind –Who did what, when? High level concepts –Repository – a source controlled location (eg folder) –Commit – writing a version to the repository –Tag – collecting certain versions of all files under a symbolic name –Branch – Split of repository for development in parallel –Merge – coercing the versions of one branch into another

A BRANCHING MODEL

LOCAL AND REMOTE You can maintain a repository under source control in two ways –Clone or copy a source controlled repository from a remote location to your machine (get the source + history) –Initialize a local project with source control When you clone a remote repository, you need to commit your changes to the remote so others can see it (a push) –They can merge your changes into their local copy (a pull)

BRANCHING In general, you branch to add something new –Example: Addition of new domain –Branch for new domain, e.g. feature/domain_vs –Commit changes to branch –Push branch to remote –Reviewer reviews changes, makes comments –Developer replies to comments, makes changes, resubmits –Reviewer merges branch into development branch

DEVELOPMENT PROCESS Following Frederik’s example –Develop a cdash-1-1-schema.rdf document (Top Braid/Protégé) Review by Team Feed any meta-model-schema changes/proposals back to Steering committee for approval (coordinate semantics across the groups) –Suggest the schema is developed collaboratively Process the CDASH specifications looking for ‘predicates’ Edit the schema in the teleconferences

CONTENT DEVELOPMENT Development of Content (cdash-1-1.rdf) –Create a spreadsheet with column headers matching the predicates (Excel/Google Docs) –Populate the spreadsheet (Excel/Google Docs) –Convert the spreadsheet to RDF (Top Braid)  cdash-1-1.rdf –Commit to repository on branch –Review

DEVELOPMENT - Logistics Logistically (Content) –Don’t want multiple versions of spreadsheets floating about –Want people to be able to modify in parallel –Google Docs? –Spreadsheet in Source Control?

NEXT STEPS Read the CDASH Specification Review the CDASH Excel Spread sheet against the Standard Document Collate all the semantic terms that we might want to model
