This is a website containing information on how to use Europeana Cloud Image Service and how to deliver data to the Image Service.
Europena Cloud Image Serivce provides access to images stored in Europeana Cloud. It is a compatible with International Image Interoperability Framework which provides a standardised method of describing and delivering images over the web. It supports images in JPEG2000 format.
The service consists of:
| Right now only TIFF to JPEG 2000 conversion is possible. This is why the instructions below will take it as example. Europeana Cloud team is currently working on providing JPEG -> JPEG2000 converter. |
Even though it is possible right now, it is highly recommended not to deliver JPEG 2000 images to Europeana Cloud but, to create a file in this format using Image Conversion Service. In this way we can be sure that the created file is fully compatible with the Image Service. It is highly probable that the ability to deliver bare JPEG2000 images to be later used in Image Service will be disabled in the future. |
To store your TIFF images in Europeana cloud - simply use Europeana Cloud API to send files to Metadata and Content Service. Please check developer's tutorial to get to know the API.
Please check out TODO LINK TO DPS TUTORIAL
The base url for Europeana Cloud IIIF server is: http://iiif.europeana.eu
Let's assume that you know your image URL e.g.
If you would visit the link above you would download a JP2000 file. If you want to view the image using IIIF viewer (embeded Europeana Cloud viewer) please:
In case of our example the link would be: http://iiif.europeana.eu/records/NXM6XJWLW5AC4ZPPIAZFQ6UDWAXLXCGFWUTMDXPPPW7RMDKVIMNA/representations/presentation_images/versions/d3139491-fcc9-11e5-bc8a-fa163e60dd72/files/node-2/image/SBB/Berliner_Tageblatt/1903/10/05/0/F_SBB_00001_19031005_032_505_0_008/
If you are using so called "friendly URLs" to access ECloud resources (check for reference TODO put link to docs of Friendly URLs here)
Let's assume this is the URL to your image in ECloud:
https://cloud.europeana.eu/api/data-providers/TheEuropeanLibrary/records/3000097619352/representations/presentation_images/node-2/image/SBB/Berliner_Tageblatt/1903/10/05/0/F_SBB_00001_19031005_032_505_0_008.jp2
Create the URL to IIIF server in the same way as previously:
In case of our example the link would be: http://iiif.europeana.eu/data-providers/TheEuropeanLibrary/records/3000097619352/representations/presentation_images/node-2/image/SBB/Berliner_Tageblatt/1903/10/05/0/F_SBB_00001_19031005_032_505_0_008
Image metadata and a list of server capabilities is available through an info.json request, which provides information on the image and the functionality provided by the image server. In order to retrieve the information file for an image simply add /info.json suffix to the end of the URL e.g.
and respectively
http://iiif.europeana.eu/data-providers/TheEuropeanLibrary/records/3000097619352/representations/presentation_images/node-2/image/SBB/Berliner_Tageblatt/1903/10/05/0/F_SBB_00001_19031005_032_505_0_008/info.json
for friendly URLs.
