About the Website Technical Overview and Acknowledgements

This website is dependent on a number of free/libre software projects and aims to make its contents available using open standards. These are detailed here to acknowledge that debt and to highlight these projects for any readers who are technically interested.

Open Standards

Open Standards in metadata allow different software to share information in a mutually intelligible way (in contrast with proprietary formats and standards, which commonly can only be read by specific commercial applications).

The archive makes use of Schema.org  structured markup to add semantic, machine-readable metadata describing organisations, publications, people etc. to our pages where relevant.

Document pages also includes COinS  and Dublin Core  bibliographic metadata, which allows software such as Zotero  and others to automatically read bibliographic information from each respective page, making it easier to add items to bibliography managing software.

Free/Libre Software

The website uses a number of Free/libre software projects. Free/libre software allows the user to use, share and modify it, without the restrictions of proprietary software ¹.

The core of the site is built with Symphony CMS  - an open source (MIT licenced) CMS which provides the site administration area and allows construction of a custom frontend with XSLT.

The frontend (i.e the pages visible to visitors) uses Bootstrap  for much of its layout and visual design.

Beyond the construction of the site itself, it runs, like much of the web, on a server that uses free/libre software projects in a combination often abbreviated to LAMP (GNU/Linux, Apache, MariaDB and PHP).

Javascript

A number of free software javascript libraries provide additional frontend functionality.

The timeline of the Irish left also uses the following JS libraries.
