OLAC Discourse Type Vocabulary
Recommendation. This document specifies the codes, or controlled vocabulary, for the Discourse Type
extension of the Type metadata element. These codes describe the content of a resource
as structured in such a way as to represent a particular type of discourse.

Specifications for the OLAC metadata display format and
the OLAC-to-OAI_DC crosswalk
Proposed Informational Note. In addition to the olac metadata format, the
OLAC Aggregator OLACA serves records in two
other formats: olac_display and
oai_dc. This document provides the
specification for how an OLAC record is transformed
into these other two formats. The first of these
formats is a reader-friendly view of OLAC metadata
that may be used by someone building a service that
displays OLAC metadata; it translates coded values
into their human-readable equivalents. The latter
format is the standard format used by the Open
Archives Initiative (OAI) for metadata interchange.
Thus the OLAC Aggregator
serves as a crosswalk that transforms the
olac format records supplied by OLAC's
participating archives to oai_dc format
records that can be used by the wider OAI
community.

OLAC Metadata Metrics
Informational Note. Explains the metrics that are implemented on the OLAC web site for summarizing the
coverage of the participating archives and for evaluating the quality of their
metadata records.

OLAC Repositories
Standard. This document defines the standards OLAC archives must follow in implementing a metadata repository.

Best Practice Recommendations for Language Resource Description
Recommendation. This document expresses the consensus of the Open Language Archives Community on best
practice recommendations for language resource description using the OLAC metadata
standard OLAC-Metadata.

OLAC Metadata Usage Guidelines
Informational Note. This document provides guidelines on the meaning and proper usage of the metadata elements used in the
metadata standard of the Open Language Archives Community.
|
2008-05-31 |
OLAC Metadata
Standard. This document defines the format used by the Open Language Archives Community
OLAC for the interchange of metadata within the framework of the
Open Archives Initiative OAI. The metadata set is based on the
complete set of Dublin Core metadata terms DCMT, but the format
allows for the use of extensions to express community-specific qualifiers.
|
2008-02-22 |
OLAC Language Extension
Recommendation. This document specifies the metadata extension used by OLAC to uniquely identify
languages. It uses the three-letter identifiers of ISO 639-3 as its controlled
vocabulary.
|
2008-02-22 |
Recommended metadata extensions
Recommendation. This document lists all the metadata extensions that are recommended by the
Open Language Archives Community for use in describing language resources.

Creating OLAC Records and Repositories in Toolbox
Draft Implementation Note. This Note presents a framework for creating OLAC static repositories from a collections of records created and maintained as a Toolbox database.
|
2006-04-06 |
OLAC Linguistic Data Type Vocabulary
Recommendation.
This document specifies the codes, or controlled vocabulary, for the Linguistic Data Type extension of the DCMI Type element. These codes describe the content of a resource from the standpoint of recognized structural types of linguistic information.
|
2006-04-06 |
OLAC Linguistic Subject Vocabulary
Recommendation. This document specifies the codes, or suggested vocabulary, for the 'linguistic' value of the xsi:type attribute of the OLAC Subject element. These codes describe the content of a resource as about a particular subfield of linguistic science, or about the level of linguistic structure which is the primary concern of a given subfield.
|
2006-04-06 |
OLAC Role Vocabulary
Recommendation. Role is an attribute of both the Creator and Contributor elements. (Please note that Dublin
Core now discourages the use of the Creator element, recommending that all Role information be
associated with Contributor elements.) This document specifies the controlled vocabulary of the
Role attribute used by OLAC. This attribute specifies the functional role of the entity named
in the creation of a given resource.
|
2006-04-05 |
OLAC Process
Standard. This document summarizes the governing ideas of OLAC (i.e. the
purpose, vision, and core values) and then describes how OLAC is organized and
how it operates.

A query facility for selective harvesting of OLAC metadata
Draft Implementation Note. Documents a verb, Query, supported by the CGI interface to the OLAC Aggregator. The purpose of the verb is to support selective harvesting of OLAC metadata, such as would be needed in order to offer a specialized service based on OLAC metadata. The request returns a ListRecords response; its parameters support the construction of an SQL query to specify the subset of records to harvest.
|
2003-07-29 |
Viser: A virtual service provider for displaying selected OLAC metadata
Draft Implementation Note. Documents a service named Viser, hosted on the OLAC web site, that allows language resource sites to post services based on OLAC metadata without having to implement a conventional service provider. Viser works in conjunction with the query facility of the OLAC Aggregator to selectively harvest OLAC metadata and then provide HTML displays of records that match a query. The service returns an XML document with processing instructions to invoke an XSL stylesheet and set certain display parameters; the actual rendering to HTML happens in the client's browser.

OLAC Protocol for Metadata Harvesting
Former Proposed Standard. This document defines the protocol OLAC service providers use to harvest metadata from OLAC data providers. It defines the responses that OLAC data providers must make to the requests of the protocol.
|
2002-12-04 |
Third Party Extensions
Draft Informational Note. This document lists third-party metadata extensions that are known
to be compatible with the OLAC Metadata standards. They have not attained the status of OLAC Recommendations, but data providers are encouraged to try any that seem relevant to the nature of their collection.
|
2002-11-19 |
OLAC Access Vocabulary
Former Draft Recommendation. Access is an attribute of the Rights element. It provides a broad classification of
the ways in which a resource may be used. Users may have to seek more detailed information
about a given resource, if Access = restricted, or if they wish to use the resource in
a non-standard fashion. Users are always advised to review the specific policies of the
data provider before making use any resource.
If the Rights element is absent, no assumptions can be made about the status of these and
other rights with respect to the resource.

OLAC Metadata Set
Former Proposed Standard. This document specifies the metadata set used by the Open Language
Archives Community OLAC for the interchange of metadata within the
framework of the Open Archives Initiative OAI.
This document is superseded by the OLAC Metadata standard:
