The Virtuoso hosted version: http://www.openlinksw.com/schemas/external/googlevocab# It receives redirects from http://purl.org/NET/googlevocab# . Why How The mapping can be initialize executing the sql file and uploading the ontology file as shown in the list below: Re-write rules creation Google Vocabulary Ontology Google Vocabulary rdf Deploying Google Mapping Vocabulary using Conductor UI: The following step-by-step guide will lead you trough the process of Deploying Google Mapping Vocabulary using Conductor UI: Go to http://<cname>:port/conductor Log in as dba user Upload the ontology file: Go to Web Application Server -> Content Management

Create folder schemas ( if does not exist already): Click the button "New folder" In the shown form: Enter Folder name: schemas Change Owner to dav Change Free Text Indexing to Recursively Click the "Create" button. As result the folder "schemas" will be created. Go to path /DAV/schemas

Click the "Upload" button. In the shown form: Change Destination to RDF Store For File click the Browse button and select the googlevoc.n3 file Enter for RDF IRI for ex.: http://www.openlinksw.com/schemas/external/googlevocab# Click the upload button

As result the file will be uploaded. Let's check the RDF data: Go to http://<cname>:port/sparql Enter the Graph IRI, for ex. http://www.openlinksw.com/schemas/external/googlevocab# Enter the following query: select * where {?s ?p ?o} Click the "Run Query" button. As result the RDF data for the given graph will be shown:

Create the virtual folder: Go to Web Application Server -> Virtual Domains & Directories For defined http host, for ex. www. openlinksw.com expand the Interface blue folder icon:

Click New Directory In the shown form select type: WebDAV doman and click the "Next" button.

In the Virtual Directory creation form: Enter Path: /schemas/external/googlevocab leave checked "Physical path is a WebDAV repository" Enter Physical path: /DAV/schemas/googlevoc.n3 Click the "Save Changes" button

As result the Virtual Directory will be created and shown in the list of virtual directories for the selected host. Create re-write rules for the created virtual folder from above: Click the URL-rewrite link for the created "/schemas/external/googlevocab" virtual directory As result will be shown the URL rewriting rules form:

Add first rule: Change "Destination Path format" to: /rdfdesc/description.vsp?g=http%3A%2F%2Fwww.openlinksw.com%2Fschemas%2Fexternal%2Fgooglevocab%2F$U1&p=googlevoc

Click the "Add" button. As result the rule will be created:

Now let's create the second rule: Change "Rule matching" to "Last matching" Enter for "Request Path pattern": /schemas/external/googlevocab/([^\.]*)$ Enter for "Accept Header Request pattern": application/rdf.xml Enter for "Destination Path format": /schemas/external/googlevocab/$U1.xml Change "HTTP Response Code" to: 303

Click the "Add" button. As result the rule will be created:

Now let's create the third rule: Change "Rule matching" to "Last matching" Enter for "Request Path pattern": /schemas/external/googlevocab/([^\.]*)$ Enter for "Accept Header Request pattern": text/rdf.n3 Enter for "Destination Path format": /schemas/external/googlevocab/$U1.n3 Change "HTTP Response Code" to: 303

Click the "Add" button. As result the rule will be created:

Now let's create the forth rule: Change "Rule matching" to "Last matching" Enter for "Request Path pattern": /schemas/external/googlevocab/([^\.]*)\.(rdf|xml|n3)$ Enter for "Accept Header Request pattern": (text/rdf.n3)|(application/rdf.xml) Enter for "Destination Path format": /sparql?query=describe%20%3Chttp%3A%2F%2Fwww.openlinksw.com%2Fschemas%2Fexternal%2Fgooglevocab%2F$U1%3E&format=$accept
