Herunterladen, um offline zu lesen

Structured Dynamics provides 'ontology-driven applications'. Our product stack is geared to enable the semantic enterprise. The products are premised on preserving and leveraging existing information assets in an incremental, low-risk way. SD's products span from converters to authoring environments to Web services middleware and to eventual ontologies and user interfaces and applications.

Structured Dynamics' Semantic Technologies Product Stack

  1. 1. May (updated) 2010 Product Stack
  2. 2. Enterprise Approach
  3. 3. Enterprise Approach <ul><li>Semantic Enterprise based on semantic Web , linked data </li></ul><ul><li>Leverage existing assets </li></ul><ul><ul><li>Data, records and instances </li></ul></ul><ul><ul><li>Taxonomies, structure and schema </li></ul></ul><ul><li>Layer semantics on to existing systems </li></ul><ul><li>Develop incrementally </li></ul><ul><li>Add sophistication, scope over time </li></ul><ul><li>Keep risks low </li></ul><ul><li>Integrate with public and Web data (“open world”) </li></ul>
  4. 4. Linked Data <ul><li>“ Linked Data is a set of best practices for publishing and deploying instance and class data using the RDF data model, naming the data objects using uniform resource identifiers (URIs), thereby exposing the data for access via the HTTP protocol, while emphasizing data interconnections, interrelationships and context useful to both humans and machine agents.” </li></ul>
  5. 5. Layers and Current Products
  6. 6. Current Products <ul><li>the pivotal product; Web services middleware that provides distributed data access and federation </li></ul><ul><li>Drupal-based structured data linkage to structWSF </li></ul><ul><li>spreadsheet, JSON and XML authoring and conversion framework </li></ul><ul><li>reference set of linking subjects and basis for domain vocabularies </li></ul><ul><li>an ontology- and entity-driven information extraction and tagging system </li></ul>
  7. 7. Fit of Current Products within Layers
  8. 8. Existing Assets Layer
  9. 9. Existing Assets <ul><li>These are the materials that need to be federated, made interoperable, and given a common semantics </li></ul><ul><ul><ul><ul><ul><li>structured data / databases </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>semi-structure data (XML, Web pages) </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>unstructured data (text) </li></ul></ul></ul></ul></ul>

  • At present, though constantly increasing, Zitgist&apos;s existing conversion services recognizes nearly 100 various formats GRDDL (Gleaning Resource Descriptions from Dialects of Languages) is a W3C markup format for getting RDF data out of XML and XHTML documents using explicitly associated transformation algorithms, typically represented in XSLT  GRDDL accomodates a wide variety of dialects (see one listing) and can be combined with arbitrary transformation mechanisms (though currently mostly based on XSLTs).
