OHMS

OAR on March 16, 2020

OHMS (Oral History Metadata Synchronizer).

Web-based, system to inexpensively and efficiently enhance access to oral history online. OHMS provides users word-level search capability and a time-correlated transcript or indexed interview connecting the textual search term to the corresponding moment in the recorded interview online.

The primary purpose for OHMS is to empower users to more effectively and efficiently discover information in an online oral history interview by connecting the user from a search result to the corresponding moment in an interview. OHMS is an open source, web-based application designed to improve the user experience you provide for oral history, no matter what CMS or repository you use. There are 2 main components of the OHMS system

OHMS Application: The OHMS application is where the work is done. This is the back-end, web-based application where interviews are imported, and metadata is created. In the OHMS application transcripts are time-coded and/or interviews are indexed. Upon completion, the interview record (including the synchronized transcript and/or time-coded index) are exported as an XML file. When located on a web server, the OHMS XML file is what interfaces with your content management system through the OHMS Viewer.

OHMS Viewer: The OHMS viewer is the user interface of ohms. When an interview is called by the repository, the OHMS viewer loads, calling select interview level metadata and the intra interview level metadata created in the OHMS Application from the corresponding xml file.

The Datahub

OAR on January 20, 2020

Sharing metadata doesn’t have to be hard. The Datahub is an application for aggregating and publishing metadata records on the web with technologies like HTTP REST and OAI-PMH. It takes care of the hard parts, so you can focus on building digital experiences for your audience.

The Datahub is an open source metadata aggregator which enables cultural organisations to share records, information and knowledge on the Web using open, standardised exchange formats such as Dublin Core.

Key features

  • A JSON based REST API with HATEOS support
  • XML Schema validation of ingested records.
  • Supports publishing records via OAI-PMH
  • Support for LIDO XML and Dublin Core formats
  • OAuth support for fine grained access control

Use case

Cultural organisations curate and store expertise and knowledge about the collections in digital formats and databases such as record management systems or collection registration systems. However, making these metadata accessible and reusable for the benefit of their audiences is a challenge.

The lack of an adaptable, maintainable, secure and cost effective infrastructure is a key obstacle. A digital architecture based on direct transfer of metadata between databases and end-user applications like websites and mobile applications, proprietary exchange formats and closed source software tools is a brittle solution.

A durable solution consists of a service oriented architecture based on a loose connection between backoffice systems and databases used to manage and preserve metadata records, and the wide array of end user applications – websites, mobile applications, visualisations, print,… – used to cater to the everchanging needs of cultural audiences.

The Datahub is an open source, web based application that sits between these backoffice systems and end-user applications and …

… ingests records structured using standardised, open formats such as Dublin Core or LIDO XML, from one or multiple datasources.
… persistently stores the ingested records in an internal database.
… publishes the stored records on the Web via a RESTful API and an OAI-PMH API.

Technical changes at the level of the datasource (i.e. a migration to a different product for records management) do not affect the audience facing consumer applications that reuse metadata to inform, to educate, to tell stories, to create new insights, to bring new user experiences.

Content ExtRactor and MINEr

CERMINE is a Java library and a web service for extracting metadata and content from scientific articles in born-digital form. The system analyses the content of a PDF file and attempts to extract information such as:

  • Title of the article
  • Journal information (title, etc.)
  • Bibliographic information (volume, issue, page numbers, etc.)
  • Authors and affiliations
  • Keywords
  • Abstract
  • Bibliographic references

Dataverse

OAR on May 14, 2019

Dataverse is an open source web application to share, preserve, cite, explore, and analyze research data. It facilitates making data available to others, and allows you to replicate others’ work more easily. Researchers, journals, data authors, publishers, data distributors, and affiliated institutions all receive academic credit and web visibility.

A Dataverse repository is the software installation, which then hosts multiple virtual archives called Dataverses. Each dataverse contains datasets, and each dataset contains descriptive metadata and data files (including documentation and code that accompany the data). As an organizing method, dataverses may also contain other dataverses.

OAI-PMH

OAR on September 27, 2018

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a low-barrier mechanism for repository interoperability. Data Providers are repositories that expose structured metadata via OAI-PMH. Service Providers then make OAI-PMH service requests to harvest that metadata. OAI-PMH is a set of six verbs or services that are invoked within HTTP.

DataCite

OAR on September 10, 2018

DataCite is a leading global non-profit organisation that provides persistent identifiers (DOIs) for research data. Our goal is to help the research community locate, identify, and cite research data with confidence.

We work on several fronts to achieve this goal. We support the creation and allocation of DOIs and accompanying metadata. We provide services that support the enhanced search and discovery of research content. And we promote data citation and advocacy through our community-building efforts and responsive communication and outreach materials.
