  17. vocabulary vocabulary vocabulary broader-term/ narrower-term relationships (shown as hierarchy) terms Metadata++ Lois Delcambre, OSU CS Colloquium Series 17

  18. Metadata++: Terms & Relationships same term may appear in more than one vocabulary – with different, even contradictory broader-term/narrower-term relationships Lois Delcambre, OSU CS Colloquium Series 18

  19. Metadata++: Terms & Relationships synonym relationships Lois Delcambre, OSU CS Colloquium Series 19

  20. Metadata++: Associative Relationships functional relationships such aswildlife-habitat relationships - supports similarity search & browsing! Lois Delcambre, OSU CS Colloquium Series 20

  21. Metadata++ • Exploiting broader-term-narrower-term • If you attach a narrow term…attach all broader terms as well • If you search for a term…search for all narrow terms as well • Support multiple hierarchies - with cross-references indicated as synonyms (as available) Lois Delcambre, OSU CS Colloquium Series 21

  27. Metadata++ • Inspired by Dublin Core, Z39.19 (Thesaurus), … • Simple, uniform model: terms & relationships • No classes • No attributes (for terms or objects) • Basic idea – broader-term/narrower-term relationship is intentionally overloaded to represent • Broader-term/narrower-term • Type – instance • Collection (set) – member • Traditional property name • Model has been formalized; query and browse capability is being defined Lois Delcambre, OSU CS Colloquium Series 27

  28. MetaData eXtract • Metadata attachment may take some time • MDX helps by suggesting terms from Metadata ++ • Results are suggested to the user … interactively The district silviculturalist at the McKenzie Ranger District on the Willamette National Forest is working on an EIS for a timber sale located within the upper McKenzie watershed. During the scoping process, the silviculturalist and rest of the IDT identified two areas in particular where the objectives would be to promote and accelerate the development of late successional characteristics over time. Both areas are located within Douglas-fir forest types; one within a Western hemlock/dwarf Oregon grape plant association, or potential vegetation type, and one in a riparian reserve that has a plant association of Western hemlock/Oregon oxalis......

The illegal advisory committee played a central role in influencing the Forest Service Decision. Issue[AppealDecision(id="1570-1-0032-10").concern(order=2)] The decision significantly reduces hunting opportunity and habitat for deer and elk. Issue[AppealDecision(id="1570-1-0035-13").concern(order=1)] The District Ranger's decision is not in accordance with the legal requirements of the National Environmental Policy Act, the National Forest Management Act, and the Forest and Rangeland Renewable Resources Planning Act. Issue[AppealDecision(id="1570-1-0038-19").concern(order=1)] Current stand condition is not adequately addressed, impacts on soil quality are not addressed, and that impacts to various species are not considered, including several late successional species, survey and manage species, and management indicator species.

  37. USDA FSEmployee name name Superimposed Schematics date id • Entity-relationship-style model is superimposed over arbitrary, base documents • Each entity, each attribute, and each relationship can be “anchored” at some text excerpt • Includes “authoritative” entities – such as for person Appeal Decision 1:1 1:1 review response 0:1 1:1 Reviewing Officer Deciding Officer title title respondent For respondent For Lois Delcambre, OSU CS Colloquium Series 37

  38. Superimposed Schematics • Represented using the uni-level description • Generic, uniform representation for structured information • Can accommodate a variety of data models (database models, XML, RDF, topic maps, …) • Can accommodate schema-first, schema-later, schema-optional information • Can accommodate multiple levels of schema-instance relationships in a single model • Based on a metamodel (with basic structures such as set, bag, list, struct, attribute, and scalar) • Logic-based language (Datalog) can easily be used to transform data (model-model, schema-schema, …) Lois Delcambre, OSU CS Colloquium Series 38

  39. What is Superimposed Information? data “placed over” existing information sources to • highlight • annotate • elaborate • select • collect • organize • connect • reuse information elements often to support new applications, beyond the original Lois Delcambre, OSU CS Colloquium Series 39

  40. Examples of Superimposed Information • Non-electronic examples: • Commentaries on religious texts, law, literature • Concordances, citation indexes • Electronic examples: • Bookmark file in your web browser • RDF metadata Lois Delcambre, OSU CS Colloquium Series 40
