1. Introduction to the Open Refine RDF tool March 2014 PwC EU Services

2. Learning objectives By the end of this module, you will have an understanding of:  How to easily describe your solutions using a pre-defined template compliant with ADMS-AP.  How to automatically transform your solutions’ descriptions into machine readable language, i.e., RDF.  How to get your interoperability solutions ready to be shared on Joinup. 2

3. How can this tutorial help you to use ADMS-AP? This tutorial shows how you can generate ADMS- AP-compliant descriptions of your interoperability solutions from a spreadsheet using the RDF extension in Open Refine.RDF extensionOpen Refine What is the ADMS-AP? The ADMS-AP (Asset Description Metadata Schema – Application Profile for Joinup) allows publishers of interoperability solutions to easily share their description metadata on Joinup using a common vocabulary, and consequently enabling the reuse possibilities of their solutions by a wider audience. “More than 35 repositories from EU Member States, EU Institutions (such as the Publications Office and Eurostat), standardisation bodies (such as W3C, CEN and the DCMI), and EU co- funded initiatives (such as e- CODEX) have shared description metadata of their interoperability solutions on the catalogue on Joinup” For more info about ADMS-AP: https://joinup.ec.europa.eu/svn/adms/traini ngs/Introduction_to_ADMS-AP.pptx 3

8. This tutorial will describe the 4 steps of the MANUAL path for transforming your interoperability solution’s description into an ADMS-AP-compliant description: 1. Use the spreadsheet template to describe your solution project, releases, packages, etc. 2. Import your spreadsheet in Open Refine 3. Add the pre-defined mappings using the Open Refine RDF extension 4. Export to RDF using the Open Refine RDF extension 8

9. 1. Use the spreadsheet template to describe your solution … getting the template Click on the following link to get the Excel template https://joinup.ec.europa.eu/elibrary/document/excel-adms-ap 9

10. 1. Use the spreadsheet template to describe your solution … understanding the template The spreadsheet template contains all concepts and fields included in the ADMS Application Profile. To describe your solution you have to fill in the different fields of the spreadsheet according to the following colour codes: 10

11. 1. Use the spreadsheet template to describe your solution … some spreadsheets refer to controlled vocabulary The following sheets help you to select the right codes when completing the classes’ fields: Asset_TypeTheme_Taxonomy Publisher_TypeTheme StatusFile_Format License_TypeGeographic_Coverage Representation_TechniqueOperating_System Interoperability_levelUser_Interface_Type LanguageProgramming_Language Example: the field “theme” in the “Asset” sheet has to be in the format “http://eurovoc.europa.eu/....” based on the controlled vocabulary described in the “Theme” sheet. “http://eurovoc.europa.eu/.... 11

12. 2. Import your spreadsheet into Open Refine … getting Open Refine and the RDF extension Download Open Refine from this link http://openrefine.org/ Note that Open Refine does not work properly on Internet Explorer Download the RDF extension from this link http://refine.deri.ie/ Install RDF extension into Open Refine following the installation guide http://refine.deri.ie/installationDocs 12

13. 2. Import your spreadsheet into Open Refine … creating your project Import the Excel file you completed in step 1 Fill in the following parameters: Create your project 13

14. 3. Add the pre-defined mapping using the Open Refine RDF extension … understanding the RDF skeleton What The Open Refine RDF extension allows you to map the current fields of your data to the required RDF structure by drawing a so-called RDF Skeleton. Why The RDF skeleton specifies how the RDF data will get generated from your own data. The cells in each record of your data will get placed into nodes within the skeleton that conforms to the ADMS-AP. How Even though it is possible to build the RDF Skeleton “manually”, it is easier here to re- apply the operation history that contains all operations required to build the RDF Skeleton from the template. 14 https://joinup.ec.europa.eu/elibrary/document/excel-adms-ap

15. … applying the operations history 1. Click ‘Undo/Redo’ > ‘Apply’ 2. Paste the operation history 3. Click “Perform Operations” 4. Click “RDF” > “Edit RDF Skeleton...” and verify that the RDF Skeleton has been created 3. Add the pre-defined mapping using the Open Refine RDF extension 15

16. … aligning the RDF schema By clicking on RDF > Edit RDF Skeleton..., you can check/modify the current mapping between your data and the RDF skeleton. 3. Add the pre-defined mapping using the Open Refine RDF extension 16

17. 4. Export to RDF using the Open Refine RDF extension … the final step Now everything is in place to generate an ADMS RDF file, containing your solution’s description. Click “Export” > “RDF in Turtle” to get an RDF description of your solution 17
