We are investigating a novel approach to data publishing that is organic in its organization, requires minimal effort from the contributor, has parsimonious design, and is accessible to all scientists as well as other potential contributorsWe offer a minimal pre-defined structure, and allow contributors to describe their data by easily defining their own metadata properties to suit their particular datasets, and to reuse common available vocabularies when it is convenient.  The normalization of metadata will be organic, as other scientists aggregate datasets in the repository and find the need to aggregate them.

=== Structured Content in a Semantic Wiki ===
+
 
+
This site uses a semantic wiki framework, [http://www.w3.org/RDF/ RDF] as the semantic representation standard.
+
We have developed it as an extension of [http://semantic-mediawiki.org/ Semantic MediaWiki] that enables contributors to use structured semantic properties to describe the contents of the wiki.   
+
 
+
Another way in which this wiki structures content is though pre-defined categories.  Pages can have special categories, which gives the wiki pages a pre-defined semantic structureSpecial categories include Task, Answer, Data, Workflow, and ExecutedWorkflow.
+
 
+
In addition, each page has a section called "Structured Properties", where contributors can specify properties and values of the topic of the page. Any contributor can define new properties on the fly.  Any contributor can change an existing property by one that is used elsewhere, effectively normalizing the use of the property across pages and therefore across objects.
+
 
+
Contributions are also structuredAt the bottom of each page, the contributors to that page are shown together with the details of their contributions to that page.  Contributors also have their own pages, which include any background information they wish to share, and where the edits that they have made are automatically summarized and shown.
+
 
+
=== Accessing Structured Content Externally ===
+
 
+
Build your own apps with the content of this wiki !
+
You can find extensive documentation about its '''[http://skc.isi.edu/odp/api.php API here]'''.
+
 
+
=== Using Structured Content to Dynamically Create Sections of Wiki Pages ===
+
 
+
Those properties can then be used to answer queries that aggregate automatically those properties and pages.  Below are some examples of how a query can be stated using those structured properties, and the automatically generated table that answers the query.  These queries can be used to create dynamically generated content.
+
 
+
==== Example: Get a List of Lakes ====
+
{{ #ask: [[Is a::Lake]]
+
| ?Area of Catchment
+
| ?Latitude
+
| ?Longitude
+
| default=No Lakes in Knowledge Base
+
}}
+
 
+
==== Get a List of Workflow Templates (limit to 5) ====
+
<pre>
+
{{ #ask: [[Category:Workflow]]
+
| mainlabel=Workflows
+
| format=broadtable
+
| limit=5
+
}}
+
</pre>
+
{{ #ask: [[Category:Workflow]]
+
| mainlabel=Workflows
+
| format=broadtable
+
| limit=5
+
}}
+
 
+
==== Get a List of Workflow Executions (limit to 10) ====
+
<pre>
+
{{ #ask: [[Category:ExecutedWorkflow]]
+
| mainlabel=Executed Workflows
+
| format=broadtable
+
| limit=10
+
}}
+
</pre>
+
{{ #ask: [[Category:ExecutedWorkflow]]
+
| mainlabel=Executed Workflows
+
| format=broadtable
+
| limit=10
+
}}
+
 
+
 
+
==== Get a List of Tasks and their Answers (limited to 5) ====
+
<pre>
+
{{ #ask: [[Category:Task]]
+
| ?Answer
+
| mainlabel=Task
+
| format=broadtable
+
| default=No Tasks in Knowledge Base
+
| limit=5
+
}}
+
</pre>
+
{{ #ask: [[Category:Task]]
+
| ?Answer
+
| mainlabel=Task
+
| format=broadtable
+
| default=No Tasks in Knowledge Base
+
| limit=5
+
}}
+
 
+
==== Get a particular Task's SubTasks ====
+
<pre>
+
{{ #ask: [[Global_distribution_of_carbon_in_lakes_and_how_they_process_carbon]]
+
| ?SubTask
+
| mainlabel=Task
+
| format=broadtable
+
}}
+
</pre>

{{ #ask: [[Global_distribution_of_carbon_in_lakes_and_how_they_process_carbon]]
+
| mainlabel=Task
+
| format=broadtable
+
| ?SubTask
+
}}
+
 
+
==== Get Tasks whose answers have some property set ====
+
<pre>
+
{{ #ask: [[Category:Task]] [[Answer.Has Dataset::2012-Dataset]]
+
  | mainlabel=Task
+
| format=broadtable

| ?Answer

Melissa,This sounds like an eixnticg venture. I'd like to see the Dublin Core Metadata Initiative in this course. The DCMI has died down quite a bit over the past few years. When it first started, it had such promise. It was groomed to be the answer for the SemWeb. But alas, it doesn't seem like it's going to work out. Or will it? The course should explore what it is, what challenges it had faced in implementation, and why it ultimately didn't work. Since it was a child of librarians, there are implications to the role (and what we've learned from the DCMI) that librarians will play in the upcoming stages of the Web. Allan
