ToolMatch Proposal 0.2

Contact: Eric Rozell

Overview: The intent of this proposal is to leverage reasoning capabilities of OWL 2 to automatically assert compatibility between tools and data collections based on the attributes of data collection. This proposal uses OWL subclass reasoning, existential reasoning, subproperty reasoning, inverse property reasoning, and symmetric property reasoning.

Use Cases

Use Case 1

• Description: Automatically match tool to a data collection based on data collection attributes.
• Purpose: Data collection providers who annotate their collections using a specific set of relevant attributes can allow users to automatically discover tools that work with those data collections. Data collection providers need only worry about annotating specific attributes of their collections. Tool providers must determine relevant attributes of a data that would determine compatible. No explicit annotation of compatibility between collections and tools is needed.
• Example: Match specific OpenLayers mapping tool to data collections accessible from a WMS.
• Generic Example: Match ToolA to data collections with attribute value AttributeX.
• Step 1: Define a subclass of toolmatch:DataCollection, toolmatch:ToolACompatibleCollection
• Step 2: Assert that any instance of toolmatch:ToolACompatibleCollection is compatible with ToolA
• Step 3: Assert that any instance with attribute value, AttributeX, is an instance of toolmatch:ToolACompatibleCollection

Stretch Use Case

• Description: Automatically match any tool from a specific subclass of tools to data collections with specific attributes.
• Purpose: This should reduce the number of steps that must be taken by tool providers to annotate their tools. Rather than determine what attributes of a data collection are relevant, a tool provider can find a class of tools similar to its own, which has already determined these relevant attributes.

Annotations

Entity	Type	Description
toolmatch:DataAccess	owl:Class	A specific attribute of a toolmatch:DataCollection. Namely, describing that a toolmatch:DataCollection is available by a specific service or in a specific format.
toolmatch:DataCollection	owl:Class	A data collection, which should be matched to toolmatch:Tool instances. It should have one or more attributes.
toolmatch:Tool	owl:Class	A broadly-defined class of tools which work with toolmatch:DataCollection instances. It should be paired with a subclass of toolmatch:DataCollection, which defines the criteria for a "compatible" toolmatch:DataCollection.
toolmatch:compatibleWith	owl:ObjectProperty	A symmetric relationship between toolmatch:Tool instances and toolmatch:DataCollection instances. In other words, a tool is compatible with a data collection, then that data collection is also compatible with that tool.
toolmatch:visualizes	owl:ObjectProperty	A subproperty of toolmatch:compatibleWith denoting a specific relationship between toolmatch:Tool instances and toolmatch:DataCollection instances. Note, this is not a symmetric property, but instead an inverse property of toolmatch:visualizedBy.
toolmatch:maps	owl:ObjectProperty	A subproperty of toolmatch:visualizes, defining a specific visualization relationship. This is an inverse property of toolmatch:mappedBy.
toolmatch:visualizedBy	owl:ObjectProperty	Defines a relationship from a toolmatch:DataCollection that can be visualized by a toolmatch:Tool.
toolmatch:mappedBy	owl:ObjectProperty	A specialization of the toolmatch:visualizedBy property.
toolmatch:hasAccessibility	owl:ObjectProperty	A property used to assert that a toolmatch:DataCollection is accessible by a given toolmatch:DataAccess instance (e.g., it's available in a specific format).
