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

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......

Querying a Superimposed Schematic

Issue [AppealDecision(id="1570-1-0032-10").concern(order=1)] The decision violates the Federal Advisory Committee Act (FACA). 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.

• Entity-relationship-style model is superimposed over arbitrary, base documents

• Each entity, each attribute, and each relationship can be “anchored” at some text excerpt

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 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 40

Examples of Superimposed Information

Non-electronic examples:

Commentaries on religious texts, law, literature Concordances, citation indexes

Electronic examples:
