---++Virtuoso Mapping Ontology for Google

---+++What

Virtuoso offers mapping ontology for Google. 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:

   1. <a href="%ATTACHURLPATH%/www.sql" style="wikiautogen">Re-write rules creation</a>
   1. <a href="%ATTACHURLPATH%/googlevoc_v4.n3" style="wikiautogen">Google Vocabulary Ontology</a>
   1. <a href="%ATTACHURLPATH%/googlevoc.rdf" style="wikiautogen">Google Vocabulary rdf</a>


---++++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:

   1 Go to http://&lt;cname&gt;:port/conductor
   1 Log in as dba user
 
Upload the ontology file:

Go to Web Application Server -> Content Management

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

<img src="%ATTACHURLPATH%/cn5.png" style="wikiautogen"/>

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

<img src="%ATTACHURLPATH%/cn6.png" style="wikiautogen"/>      
        
As result the file will be uploaded. 

Let's check the RDF data:

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

<img src="%ATTACHURLPATH%/cn7.png" style="wikiautogen"/>

Create the virtual folder:

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

<img src="%ATTACHURLPATH%/cn1.png" style="wikiautogen"/>

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

<img src="%ATTACHURLPATH%/cn2.png" style="wikiautogen"/>

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

<img src="%ATTACHURLPATH%/cn3.png" style="wikiautogen"/>

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:

   1 Click the URL-rewrite link for the created "/schemas/external/googlevocab" virtual directory
   1 As result will be shown the URL rewriting rules form:

<img src="%ATTACHURLPATH%/cn8.png" style="wikiautogen"/>

Add first rule:

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

<img src="%ATTACHURLPATH%/cn9.png" style="wikiautogen"/>

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

<img src="%ATTACHURLPATH%/cn10.png" style="wikiautogen"/>

Now let's create the second rule:

   1. Change "Rule matching" to "Last matching"
   1 Enter for "Request Path pattern": 
<verbatim>
/schemas/external/googlevocab/([^\.]*)$ 
</verbatim>
   1 Enter for "Accept Header Request pattern": application/rdf.xml
   1 Enter for "Destination Path format":
<verbatim>
/schemas/external/googlevocab/$U1.xml
</verbatim>
   1 Change "HTTP Response Code" to: 303

<img src="%ATTACHURLPATH%/cn11.png" style="wikiautogen"/>          
  
   1 Click the "Add" button.
   1 As result the rule will be created:

<img src="%ATTACHURLPATH%/cn12.png" style="wikiautogen"/>

Now let's create the third rule:

   1 Change "Rule matching" to "Last matching"
   1 Enter for "Request Path pattern": 
<verbatim>
/schemas/external/googlevocab/([^\.]*)$
</verbatim>
   1 Enter for "Accept Header Request pattern": text/rdf.n3
   1 Enter for "Destination Path format":
<verbatim>
/schemas/external/googlevocab/$U1.n3
</verbatim>
   1 Change "HTTP Response Code" to: 303

<img src="%ATTACHURLPATH%/cn13.png" style="wikiautogen"/>        
    
   1 Click the "Add" button.
   1 As result the rule will be created:

<img src="%ATTACHURLPATH%/cn14.png" style="wikiautogen"/>

Now let's create the forth rule:

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

<img src="%ATTACHURLPATH%/cn15.png" style="wikiautogen"/>           
 
   1 Click the "Add" button.
   1 As result the rule will be created

<img src="%ATTACHURLPATH%/cn16.png" style="wikiautogen"/>
