Metadata services
ADS offer a range of services which allow machine readable access to the metadata we hold. In addition our metadata is shared with a number of external services and catalogues.
OAI-PMH
The ADS provides an OAI-PMH target for other archives or interested parties to harvest information from our repository. To harvest the data from our target, a harvester must be built and pointed at one of our endpoints. You can find out more about setting up an OAI-PMH and building your own harvester at the links below:
The ADS currently has three targets; archives, journals, and oasis. The ADS also publishes one target for Internet Archaeology articles.
Archives:
Includes predefined sets (optional constructs for grouping items) created for specific funders such as MEDIN and NERC, and also a number of UK Higher Education organisations for retrieval of their own projects.
| Endpoint: | http://archaeologydataservice.ac.uk/oai/archives/OAIHandler |
| Schemas: | oai_dc, ads_archive, nerc_dds, medin_ddp |
| Sets: | ALL, LONDON, NERC, MEDIN, OXFORD, BRISTOL, UCL, SOTON |
| Sample Identifier: | oai:archaeologydataservice.ac.uk:COLL_ID_1000762 |
Journals:
| Endpoint: | http://archaeologydataservice.ac.uk/oai/journals/OAIHandler |
| Schema: | oph |
| Set: | ALL |
| Sample Identifier: | oai:archaeologydataservice.ac.uk:JNL_1000787 |
OASIS:
Inlcudes a predefined set (optional constructs for grouping items) created for MEDIN for all maritime reports.
| Endpoint: | http://archaeologydataservice.ac.uk/oai/oasis/OAIHandler |
| Schema: | medin_ddp |
| Set: | ALL, MEDIN |
| Sample Identifier: | oai:oasis.ac.uk:wessexar1-4936 |
Internet Archaeology:
Inlcudes a predefined set (optional constructs for grouping items) created for MEDIN for all maritime reports.
| Endpoint: | http://intarch.ac.uk/oai/articles/OAIHandler |
| Schemas: | oai_dc, medin_ddp |
| Sets: | ALL, MEDIN |
| Sample Identifier: | oai:intarch.ac.uk:COLL_ID_1001303 |
Linked Open Data
The ADS Linked Open Data are made available as a direct result of the STELLAR project, a joint venture between the University of South Wales, the ADS and Historic England (formely known as English Heritage).
The ADS Linked Data repository contains triples for each ADS Archive.
The ADS also provides a SPARQL query web interface which can be used to interrogate the ADS triple store directly. However, interacting with SPARQL endpoints, is much easier and more fruitful, using one of the many SPARQL clients available.
External Services and Delivery
A growing number of external services consume our metadata. For Objects this is primarily for documents such as unpublished reports and journal articles.
ARIADNE
The ARIADNE Portal brings together archaeological research datasets from ARIADNE partners from Europe and beyond.
The ADS supply all Archsearch Inventory datasets, all records of unpublished reports, andall records for Archives to ARIADNE. Data is mapped to the ARIADNE AO-Cat, an application profile of the CIDOC CRM, and exported as XML. The subject terms used by the ADS (commonly UK heritage thesauri) have all been mapped to The Getty Art and Architecture Thesaurus, which is used as the spine of the ARIADNE model.
ADS Datasets can thus be cross-searched with equivalents from across the world. Each metadata record (for example this record from the NRHE Excavation Index) provides a link back to the original ADS resource, an option to Cite the record using the ADS DOI or URI, and and a statement covering the Terms and Conditions of Use. The metadata is available to download as JSON or XML in the Ariadne Data Model.
MEDIN (Marine Environmental Data and Information Network)
Metadata for maritime archives is exported out of the ADS CMS and supplied as XML in the MEDIN Metadata Schema to the MEDIN Data Portal.
Metadata for OASIS reports is made available as a distinct set within an OAI-PMH target (see above).
ADS Archives and OASIS reports can thus be cross-searched alongside other subject areas such as Oceanogrpahy and Flora and Fauna. Each metadata record (for example see the record for HMS Colossus) contains the DOI linking back to the ADS website, and a statement covering the Terms and Conditions of Use. The metadata is available to download as XML in the MEDIN Schema, and Dublin Core (DCMES).
NERC
The NERC Data Catalogue Service provides access to all NERC funded datasets. Via the OAI-PMH Archives target, ADS shares metadata of all NERC project datasets it holds. Access to this metdadata is via the Data Catalogue, where it can also be downloaded in a variety of formats including XML and RDF.
Heritage Gateway
All English inventory records held in Archsearch are made avialable to the Heritage Gateway as a SOAP Web Service and Web Map Service (WMS). Heritage Gateway resources are reploaded periodically, upon the request of the Depositor.
DataCite
Each Archive, and most OASIS reports and Journal Articles have a DOI assigned via DataCite. Metadata is supplied in the DataCite Metadata format, via the DataCite API. ADS maintain responsibility for updating metadata, usually upon any sigifncant change or correction. DataCite metadata can be freely accessed, and downloaded as XML, JSON, and JSON-LD.
Keepers Registry
Each Archive, and most OASIS reports and Journal Articles have a DOI assigned via DataCite. Metadata is supplied in the DataCite Metadata format, via the DataCite API. ADS maintain responsibility for updating metadata, usually upon any sigifncant change or correction. DataCite metadata can be freely accessed, and downloaded as XML, JSON, and JSON-LD.
