Old Talk And Old Content

What about importing DOAP(description of a project): http://trac.usefulinc.com/doap to be used with project pages similarly to foaf with userpages. It is meant for software projects, but I don't think there is anything major preventing it from being used in a broader context.

Looks interesting, should look into that as well. --Kwisatz 16:46, 29 December 2009 (UTC)

The other question is that should we not mention the free semantic wiki host referata.com (which our space is adopting)? more on that on my talk page --User:Elmom

Local events should be entered on the own wiki, all external events on this one. There is a problem though, that we will probably not be able to solve using the ExternalData extension:

RandomSpace.xyz <-- [fetch semantic data] --- Hackerspaces.org <-- [fetch semantic data] --- AnotherRandomSpace.abc

This will result on RandomSpace.xyz only displaying events from the hackerspaces.org database, as all other data is only fetched, parsed and displayed, but not imported.

Suggested solutions

• Using Semantic MW: http://www.mediawiki.org/wiki/Extension:External_Data#Using_External_Data_with_Semantic_MediaWiki
• A different extension: Data Import Extension which would require testing though.
• Enter all events only on hackerspaces.org

Properties

Events currently have the following properties on hackerspaces.org:

• Property:Start date
• Property:End date
• Property:Min Cost
• Property:Max Cost
• Property:Venue
• Property:has location city
• Property:has location state
• Property:has location country
• Property:Homepage
• Property:subevent of
• Property:Event type
• Property:Has coordinates
• Property:workshop deadline
• Property:abstract deadline
• Property:paper deadline
• Property:tutorial deadline
• Property:poster deadline
• Property:demo deadline
• Property:submission deadline
• Property:notification
• Property:Event in series
• Property:Camera ready due

They have the following properties on i.e. syn₂cat:

• Property:StartDate
• Property:EndDate
• Property:Has date
• Property:Is External
• Property:Is Recurring
• Property:Has Contact
• Property:Country
• Property:State
• Property:City
• Property:Cost
• Property:Url
• Property:Location
• Property:Has coordinates

A coordinated approach would have at least the following properties:

• Property:Start date (Date)
• Property:End date (Date)
• Property:Min Cost (String)
• Property:Max Cost (String)
• Property:Venue (String)
• Property:State (String)
• Property:City (String)
• Property:Country (String)
• Property:Homepage (URL)
• Property:Has coordinates (Geographic Coordinates)
• Property:Event type (String: list of allowed valued: x,y,z)
• Property:Subevent of (Page)

Test / Example

This is live data from hackerspace.lu

{{#get_external_data:https://www.hackerspace.lu/wiki/Special:Ask/-5B-5BCategory:ExternalEvent-5D-5D-0A-5B-5BIs-20Recurring::no-5D-5D-0A-5B-5BEndDate::-3E2010-2D01-2D2-2000:00-5D-5D/-3FStartDate%3DFrom/-3FEndDate%3DTill/-3FLocation/-3FUrl/sort%3DStartDate/order%3DASC/format%3Dcsv/sep%3D,%7CCSV with Header|event=|from=From|till=Till|url=Url}}

Preferred: Using Special:Ask

This is how we do it...

asking for events from our wiki
{{#get_external_data:https://www.hackerspace.lu/wiki/Special:Ask?title=Special%3AAsk&q=[[Category%3AEvent]]%0D%0A[[StartDate%3A%3A%2B]]&po=%3FStartDate&sc=0&eq=yes&p=format%3Dcsv&sep=%3D,|CSV with Header|event=|startdate=StartDate}}
{{#for_external_table:{{{event}}} starts on {{{startdate}}} <br/>}}

asking for external data from hackerspaces.org
{{#get_external_data:http://hackerspaces.org/wiki/Special:Ask?title=Special%3AAsk&q=[[Category%3AEvent]]%0D%0A&po=%3FStart%20date%0D%0A%3Ftitle%0D%0A&sc=0&eq=yes&p=format%3Dcsv&sep=%3D,|CSV with Header|event=title|startdate=Start date}}
{{#for_external_table: * {{{event}}} has {{{startdate}}} <br> }}

asking for opendoors startdate from our wiki
{{#get_external_data:https://www.hackerspace.lu/wiki/Special:Ask/-5B-5BOpenDoors-5D-5D/-3FStartDate/-3FEndDate/format%3Dcsv/sep%3D,|csv with header|sdate=StartDate|edate=EndDate}}
* Opendoors has StartDate {{#external_value:sdate}} and ends on {{#external_value:edate}}

We've learned how to extract event name and "Event Start Date" from hackerspaces.org, the syntax is disgusting though: hackerspace.lu sandbox

As you can see, events should always define the "Title" field, otherwise they look a bit blank. --Tschew 14:02, 20 September 2009 (UTC)

SSL trouble

We had to modify the external data extension to support SSL: (change should have been included upstream by now) [note that VERIFYPEER=false is a bad idea, but needs to be set because of a libcurl bug: http://bugs.php.net/bug.php?id=43158] --Kwisatz

ED_Utils.php:

287                 if( !isset( $edgCacheTable ) || is_null( $edgCacheTable ) )
288                         return Http::get( $url, 'default', array(CURLOPT_SSL_VERIFYPEER => false) );

Alternative: The RDF export

Howto: http://semantic-mediawiki.org/wiki/Help:RDF_export#Exporting_all_data

You may want to use a daily/hourly cronjob to dump the entire RDF info:

#!/bin/sh
logger -t syn2cat "Dumping rdf data..."
DOCROOT="[your docroot here]"
SCRIPT="w/extensions/SemanticMediaWiki/maintenance/SMW_dumpRDF.php"
OUTPUT="${DOCROOT}/RDFout"

`which php` ${DOCROOT}/${SCRIPT} -o ${OUTPUT}
