Background

facts about wiki

A Wiki is a well-known platform for collaborative knowledge management.
The Wiki allows users to encode data, data process logs, and policy in individual wiki articles
The Wiki allows users to link pages and browse by hyperlink surfing in both way

facts about semantic wiki

Semantic Wiki assists users to better organize/access knowledge
- knowledge can be authored in semantic wiki syntax and directly exported as RDF, which is a Semantic Web standard language.
- knowledge can be organized in more structured ways (not just free text) via, for example, semantic forms and semantic templates.
- knowledge can be retrieved by structured semantic queries.

Encoding Data Semantics

For each named entity identified in TAMI scenario, we can create a wiki page to host its metadata. For example,

a person: Oscar Grace
a data record: Request 5-1: Motor Vehicle/Vessel Records Request Form

For each TAMI transaction log event, we can

encode it as an Category:Event, e.g. St. Lucie Police Log Event 5
group it using Category:Transaction_Log, e.g. St. Lucie Police Log

For laws, we can

encode each individual law entry as a Category:Policy, e.g. FS_119_01_1
group it using Category:Law, e.g. a state law: Florida Sunshine Law - Public Records

Linking Data

from page to page: user can use wiki's native feature to list pages linking to the current page, e.g.

 Special:WhatLinksHere/Policy Testbed Tutorial

from page to page semantically: semantic wiki allows users to specify the semantics of the hyperlink

  Detective Oscar Grace is the Property:Coordinator of the event (see Special:Browse/St._Lucie_Police_Log_Event_5)

use query result to establish link: semantic wiki also allows users to display semantic data to any page via semantic query

  a table is generated on St._Lucie_Police_Log by the following semantic query

   {{#ask: [[Category:Event]][[log::{{FULLPAGENAME}}]] 
    |?datetime |?coordinator |?operation |?participant |?input data  |?output data |?cause  |?cause of  
    |sort=datetime
   }}

from data to policy: user may add links to relevant rules in a log entry using light-weight query
