| - | ==== - Extracting RDF metadata [5 minutes] ==== | ||
| - | Semantic Web-aware tools and technologies are around... | ||
| - | - Annotating flickr images: | ||
| - | - Open <wrap caution>[[http://www.kanzaki.com/works/2016/pub/image-annotator|Image Annotator]]</wrap> | ||
| - | - Enter URL for some image you like | ||
| - | - Select some regions on the picture and add descriptions for them | ||
| - | - Generate file using "Show JSON-LD" button | ||
| - | - Analyse the file. How regions' information is represented? Copy the source into the [[#report]] 8-). | ||
| - | |||
| - | ==== - Common Vocabularies [10 minutes] ==== | ||
| - | - Acquaint yourself with the following vocabularies: [[http://www.w3.org/TR/skos-primer/|SKOS]], [[http://www.dublincore.org/metadata-basics/|Dublin Core]], [[http://xmlns.com/foaf/spec/|FOAF]] | ||
| - | - 8-) Answer the questions: | ||
| - | - What is each vocabulary for? | ||
| - | - What applications use them? | ||
| - | - Browse thruogh more semantic vocabularies [[http://esw.w3.org/TaskForces/CommunityProjects/LinkingOpenData/CommonVocabularies|here]]. Choose one vocabulary and describe it shortly in your report 8-). | ||
| - | |||
| - | ==== - FOAF [10 minutes] ==== | ||
| - | - Create your FOAF file with: <wrap caution>[[http://www.ldodds.com/foaf/foaf-a-matic|foaf-o-matic]]</wrap> | ||
| - | - Save your FOAF file. Put it in the report 8-). | ||
| - | - Publish your file so that it can be referenced with URL. Put the URL into the report 8-) | ||
| - | - Visualize your FOAF file with <wrap caution>[[http://foaf-visualizer.gnu.org.ua/|FOAF.Vix]]</wrap>. Simply put the URL as an ''uri'' argument to the FOAF.Vix, e.g.: http://foaf-visualizer.gnu.org.ua/?nocache=1&uri=http://home.agh.edu.pl/~kkutt/foaf.rdf | ||
| - | - Add more friends using their FOAF files. Visualize again. | ||
| - | |||
| - | ==== - Linked Open Data [20 minutes] ==== | ||
| - | - Read about the [[http://en.wikipedia.org/wiki/Linked_Data|Linked Data]] idea (and the [[http://www.w3.org/DesignIssues/LinkedData.html|original note by T. Berners-Lee, plus the 5 star system]]) | ||
| - | - Go the the webpage of the [[http://esw.w3.org/SweoIG/TaskForces/CommunityProjects/LinkingOpenData|Linking Open Data]] project. | ||
| - | * Analyze the [[http://lod-cloud.net/versions/2014-08-30/lod-cloud_colored.svg|clickable LOD diagram]], choose 5 datasets and in a few words describe them in the report (what information do they contain?) 8-) | ||
| - | |||
| - | ==== - Semantic Web tools and applications [30 minutes] ==== | ||
| - | |||
| - | Browse the following websites and get to know various Semantic Web tools and applications: | ||
| - | - 8-) [[http://www.w3.org/wiki/ConverterToRdf|ConverterToRdf]]: which in your opinion are the most important? What Converter would you add (converting from what format)? | ||
| - | - 8-) [[http://esw.w3.org/TaskForces/CommunityProjects/LinkingOpenData/SemWebClients|Linked Data Browsers]]: how many of them are up and running? | ||
| - | - 8-) [[http://www.mkbergman.com/sweet-tools/|Sweet Tools]]: select one Annotator (tool for semantically annotating resources; you can simply put "Annotator" in search box) and describe it's capabilities. | ||
| - | - 8-) Choose one application from [[http://readwrite.com/2009/12/02/top_10_semantic_web_products_of_2009|Top 10 Semantic Web Products of 2009]] or [[http://readwrite.com/2010/12/29/top_10_semantic_web_products_of_2010|Top 10 Semantic Web Products of 2010]], read more about it and describe why this one is considered as Semantic Web application. | ||
