Jumper Index is a central, shared registry server for referencing structured
data in a highly distributed environment. The Jumper Index stores the metadata associated with the data to provide
context, structure, and meaning to the data. It provides a central reference to fragmented but highly specific pieces of
data stored in any distributed and heterogeneous database regardless of the schema or structure of the data. A Jumper
provides a single consolidated view for delivering visibility to these organizational or global assets.
Jumper Index contains more than just a reference to the data. Jumper delivers the first real
technology that can be used to solve data discovery and data integration problems across the vast life sciences
data landscape. A Jumper Index can be accessed from any RDF browser, although the JUMP browser allows you to view additional
JUMP-OWL data profile information.
Jumper Index provides a suite of open-source software modules. These modules consist of
tools for extracting metadata from structured data and putting it in a JUMP-OWL (Web Ontology Language) format, a
professional editing tool for building and debugging ontologies, and a powerful indexing and searching capability to
locate precise data from disparate and fragmented databases located across your organization or the Internet.
Jumper Index tools:
- an open-source extraction tool that connects to any relational database using a standard
JDBC-Connection and mediates between the relational and the semantic context. It converts a database schema
automatically into a JUMP-OWL ontology and presents a holistic representation of both the column names as well as
the physical and technical metadata that define the columns.
- an open-source editing and debugging tool with a familiar web-browser interface to build and
edit JUMP-OWL ontologies, check for errors and inconsistencies (using a reasoner), browse multiple ontologies,
determine equivalencies between ontologies (using OWL ‘same as’ predicate), and share and reuse existing data by
establishing mappings among different ontological entities.
- an open-source indexing tool for fast, flexible, searching of multiple distributed databases. It
provides a complete system for indexing collections of structured data with a powerful tool for searching and retrieving
information about structured data using JUMP-OWL knowledge representation formats. Indices are based on JUMP-OWL files
that describe the structured knowledge represented in database table schemas and metadata profiles using an extension of
the Web Ontology Language called JUMP-OWL and indexing these files to provide a search capability.
Jumper Index is not your typical metadata server. It is a powerful semantically driven metadata
management server that provides unique capabilities to manage the constantly expanding, dynamic, often very large,
distributed bioinformatics datasets. A Jumper can contain any descriptive information entity (e.g., models, metadata,
annotations, schemas, indexes, etc.) that are available to describe structured data. It captures these in a set of
standards based knowledge representational languages (OWL, JUMP-OWL, RDF, N3, D2RQ) that are used to represent the
knowledge of a data domain in a structured and formally well-understood way.
Jumper Index is an RDF/OWL compatible server. It can be searched by any RDF/OWL browser. The
Web Ontology Language (OWL) and the Resource Description Framework (RDF) are World Wide Web Consortium (W3C) Recommendation
standards.
