Please re-use the data in any way you see fit. It is released under the Public Domain Dedication and License 1.0. We make no claim of copyright over either the data we have collected ourselves, nor the hundreds of hours of collective value added by our co-curators. That said, we can accept no liability for any issues that may arise over the re-use of this data, and you are advised to make your own assessment. Geo locations are obtained either from the position data of a Creative Commons licenced image or through manual geocoding by our volunteer co-curators. We regard all of our data to be clean of copyright and 100% in the Public Domain.

We do not store photographs on our site. Instead, we connect and add context to existing resources on the web. We supply links to images that you could display within your own app with the appropriate attribution. Some images are 'non-commercial' and you should decide whether to display them or not.

We love it when you acknowledge Open Plaques and link back to us - but you are under no obligation to do so.

We obtain information from local lists on the internet (council web sites, civic society pages, etc). We do not copy from other plaque collecting sites. We ask other sites to accord us the same respect.

What data is available? datadumps in different formats

Datadumps are run on an ad-hoc basis. Plaque id numbers do not change, but we occasionally delete a duplicate record. Fields are fairly stable, but subject to change. You might want to design your app so that you can reload data from the next update. Tell us if you have difficulty loading or manipulating any of these datadumps. We cannot fix what we do not know.
