Ontology for Open Data Web (voc4odw)
Andrea Wei-Ching Huang, Cheng-Jen Lee and Tyng-Ruey Chuang, Institute of Information Science, Academia Sinica, Taipei, Taiwan.
This document describes an ontology for publishing Linked Data in the Open Data Web (data.odw.tw). The initial ontology is being designed for implementing CC licensed data from the Union Catalog of Digital Archives Taiwan . However, the core model of the ontology is flexible and adaptable for other uses in curating, publishing and reusing their data according to users’ context.
In the Corer Model, the Refined Data (data:Refined) requires Event concepts to interpret its meanings.
PlainLiteral used only because the date value is not cleaned and nomalized.
URL of the resource from http://catalog.digitalarchives.tw/
Agent ID, and are mostly mapped with wikidata ID.
Event ID list. Two main categories of events are distinguished as Known Event and Un-known event.
Unknown Event ID.
9 event types are in current dataset. An event type belongs physical creation process will have event type id as evt84:phyCre-dOID. A digital publication process will be classified with event Id like evt84:digPub-dOID.
Project ID, and are mostly mapped with wikidata ID.

data:Provenance uses r4r:Provenance as key component model to be packaged with the reused data publishing in data.odw.tw.
漢籍全文
A derivation data extracted something from data:Reused to enrich semantics of the resource. Semantic meanings of different interpretations are provided from conceptual model. Different interpretations or different derivation processes are curated in different refined versions (ex. r1, r2, r3...).
學術社會應用推廣
A derivation data extracted something from voc:PrimaryData. For instance, the unique subject resource in the data.odw.tw which reuse primary source and support semantic enrichment for derivation data (refined data).
拓片
The main data ID, the starting resource in current data.odw.tw, and represents data:Reused resource. OID is the key to connect original catalog metadata.
List of the mapped resource from external. ex. ID from wikidata, Geonames or The Encyclopaedia of Life (EOL).
Provenance resource ID, and normally with date information about its generation time.
Directory of data classified in theme (currently in 14 domains)
Statements of refined semantics from data:Reused. Versions of refined objects will be represent with namespace: r1, r2,r3...
A vocabulary used in the linked data cloud.\" from original authors. We use voaf:Vocabulary as a main Class to relate the Core Model to external common vocabularies. Some hierarchy relations can be traced in this class
A created collection of Creative Works or other artefacts. Defined in the bib.schema.org extension.
Categories of physical activity, organized by physiologic classification. The term 'PhysicalActivityCategory' is not in the schema.org core vocabulary, but is defined in an extension:
Records of item collections organized and curated in a systematic order.
Type of resource ID in data.odw.tw.
Interpretation from common knowledge vocabulary like Schema.org.
The conceptual model incorporates SKOS and explains connections to the key event concept which is contextualized by common or domain knowledge vocabularies.
Context is contextualized by common or domain knowledge vocabularies.
The Core Model is responsible for the key structure to linked data publishing at the Open Data Web.
voc:DataModel represents key data structure and relation separated from conceptual level concepts. A framework to illustrate data's primary source, derivation and provenance statements.
A data resource obtains something from a specified primary source through specific rules.
Interpretation from domain knowledge vocabularies like Art and Architecture Thesaurus (AAT) and Darwin Core Terms (dwc).
A main concept to relate people, place and time. An event resource can be a statement about human-associated process like birth without spatio-temporal descriptions; or a spatial entity like an unknown event locate in some place; or an unknown event as a temporal entity with time descriptions.
Event concept is being recognized from specific field description of the primary data. For instance, data of the photo taken in a photo event, place of the object created in a creation event, or people who are involved in a specific event.
voc:Objects are groups of SKOS concepts for event's factors and products.
Data curated and published in response to the global demands on public access to data. For high-level requirements of reproducibility, the component and mechanism design are in the packaging of articles, data and code.
A concept to combine agent, person, organization and project. An event resource can be a statement about human-associated process like birth without spatio-temporal description.
Place combines concepts like Place, Location and Spatial Thing. An event resource can be a statement about a spatial entity like an unknown event locate in some place.
Original resources which support the derivation of data.
The original sources, most of time are from the original data creators.
Time combines concepts like temporal entity, date, period, time instance, and interval. Thing. An event resource can be a statement about a temporal entity like an unknown event happened at some time.
Event concept not or not yet be recognized from specific field description of the primary data.
