Teranode Tools and Platform for Pathway Analysis
  • Michael Kellen, Solution Manager
  • June 16, 2006

2
Teranode Introduction
  • A software company providing tools to support
    research and development in the life sciences
  • Founded on University of Washington technology in
    2002
  • Series B venture-backed
  • Headquarters Seattle, WA Regional Office
    Boston, MA
  • 40 Employees

Science advances through the informal
collaboration within distributed and fluid
communities

So Many Applications, So Few Resources!
7
The Data Reuse Challenge Time
  • Source software, APIs, and even IT standards
    become obsolete
  • Changing scientific requirements break
    pre-defined application schemas
  • Data, and especially the context needed to use it
    become lost

8
Information exchange, especially between domains,
ends up being document-driven

Existing Web provides data access but not data
integration
10
The Semantic Web promises automated data
integration through flexible, evolvable data
models

11
Key Semantic Web Technologies
  • URIs like Life Sciences Identifiers (LSIDs)
    provide standard ways to reference resources
  • Resource Description Framework (RDF) provides a
    way to describe new relationships between data
    sets without changing old schemas
  • Web Ontology Language (OWL) allows scientists to
    formally specify how knowledge is structured for
    a particular domain

12
Life Sciences Identifiers (LSIDs)
  • A standard way to describe life sciences
    resources
  • Identifies a resource through 3-4 properties
  • The authority issuing the identifier
  • A namespace
  • An object ID
  • An optional revision ID
  • urnlsidteranode.compathways9203901234980
  • A resolution service provides LSID resources on
    the internet
  • Is a standard service defined by the OMG
  • Usable by both computer agents and humans
  • Provides the resource data
  • Provides metadata about the resource

13
Teranode's LSIDResolution Service
  • TMS repositories are described by LSIDs
  • Any number of TMS repositories
  • TMS repository LSID namespace
  • All TMS documents have an LSID
  • All TMS documents are accessible

RDF Benefits
  • Built on URIs to leverage web
  • Machines can automatically assemble relevant
    information
  • New information doesnt break old relationships
  • Can be built bottom-up by referencing existing
    data sources

17
Teranode Object Model
  • VLX/RDF describes annotated, directed graphs
  • Typed nodes and edges
  • Hierarchy
  • Arrays
  • Embedded mathematics engine
  • Nodes and edges are annotated with typed
    properties

18
OWL for scientific ontologies
  • Built on RDF, OWL allows further specification of
    data types and relationships between data types
  • Can also represent business layers
  • Legal rights
  • Versioning
  • Corporate standards

19
Teranode Type Dictionary
  • Type Dictionaries can be created through Teranode
    Kernel API
  • Create dictionary
  • Define property, node, edge, graph types
  • Save dictionary as .owl
  • Load dictionary from .owl
