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.

ImageSnippets

OAR on December 23, 2019

ImageSnippets is an archival and curation tool. The goal of ImageSnippets is to build a persistent resource that establishes provenance and preserves the historical content and context of images. The application uses RDF syntax to ensure that the data entered will be readable in the future. RDF has become a standard, like HTML, and will likely be read by semantically aware devices for years to come. Additionally, the application saves data in a way that cannot be easily manipulated.

How much does it cost to join?

Right now it is free, because it is still in beta and we want to gain experience with its use and get feedback from early adopters. In the future we plan to add features such as privacy options and enterprise portals, for which we will charge a fee from commercial users. Researchers and curators working for nonprofits will always have free access to the basic ImageSnippets system.

GeoNode, geospatial content management system

OAR on July 8, 2019

GeoNode is a geospatial content management system, a platform for the management and publication of geospatial data. It brings together mature and stable open-source software projects under a consistent and easy-to-use interface allowing non-specialized users to share data and create interactive maps.

Data management tools built into GeoNode allow for integrated creation of data, metadata, and map visualizations. Each dataset in the system can be shared publicly or restricted to allow access to only specific users. Social features like user profiles and commenting and rating systems allow for the development of communities around each platform to facilitate the use, management, and quality control of the data the GeoNode instance contains.

It is also designed to be a flexible platform that software developers can extend, modify or integrate against to meet requirements in their own applications.
