Deliverable: Europeana Creative D3.3 Extension of the Europeana Licensing Framework

1. Some context

1.b what is ‘quality’ these days?

apple promo image (5120*2880px) on retina 5k imac

detail from the nightwatch (14K * 13K pixels)

downloaded image from Thyssen-Bornemisza Museum (1000*997 px)

same image relied to fit Europeana thumbnail size (200*150px)

same image resized to 800*600px (very common image size)

compared with non retina iPad screen

compared with high end android telefoon screen (1920*1080px - full HD TV)

compared with screen of a macbook air

compared with retina macbook screen

compared with retina iPad screen

2048px

1536px

The screen size of a retina iPad is probably a good departure point for determining what “good enough” means when providing images that you want others to enjoy and possibly to re-use.

To stay relevant we need to be ahead of the curve

we need to be here

2. Current situation

Europeana currently exposes digital objects via 3 display modalities

1. Via the portal at www.europeana.eu 2. Via the portal with added Lightbox functionality

3. Via the Europeana API

(2) requires a direct link to the digital object, (3) works best with a direct link. also a direct link to an image is required for preview generation. there are (at least) two types of direct links (edm:object and edm:isShownBy).

Europeana has no clear guidelines for (image) quality.

1. Previews need to be at least 200px (but are not required)

2. There is no minimum size requirement/recommendation for exposure via Lightbox or via the API.

The same is true for the quality of other types of objects. However this issue us most pronounced with images (and to a lesser degree video)

this is confusing*

* i am saying this for the perspective of promoting content re-use, but it is probably confusing in many other situations as well.

3. A new approach

The taskforce recommends a ‘differentiated service approach’, based on the needs of the data partner with a clear connection between what the partner wants, delivers and gets.

Europeana Publishing Framework

1. Europeana as search engine

ObjectLinkMDataLicense

>400 pxindirectBasicAny

Communicate:

We recommend that you provide previews with a minimum of 400 pixels wide (0.25M). These will be the ones that will show up first and prominently in a search on the Europeana portal.

2. Europeana as publication channel

ObjectLinkMDataLicense

>800 pxDirect+Any

Communicate

We will showcase images with a Minimum of 800 pixels wide (0.5 M) on a channel. Relevant content of lesser size will remain discoverable.

3. Europeana as a distribution platform for non-commercial use

ObjectLinkMDataLicense

>1200 pxDirect++Any

Communicate

We actively distribute images that are made available under a rights statement that allows reuse (all CC licenses, CC0, PDM & OOC-NC). We recommend images with a minimum of 1.200 pixels wide (1M).

Relevant content of lesser size remains available through the europeana portal and the API

4. Europeana as a free re-use platform

3d. Europeana as free re-use platform

>1200 pxDirect++CC0/PD/CC-BY/

CC-BY-SA

Communicate:

We actively distribute images that are made available under a rights statement that allows free reuse (CC-BY, CC-BY-SA, CC0, PDM). We recommend images with a minimum of 1200 pixels wide (1M).

Summary

If you want to use Europeana as a discovery mechanism that allows users to find your content we recommend you provide a preview of min 400px

If you want to use Europeana as a publication channel then you need also need to provide a direct link to the digital objects (we advise a min of 800px)

if you want to use Europeana as a distribution platform for re-use you need to provide a direct link to the digital object (we advise min 1200 px) and a rights statement that allows reuse.

If you want to use Europeana as a free re-use platform you need to provide a direct link to the digital object (we advise min 1200 px) and a rights statement that allows free reuse.

5. To discuss

Discussion points

Is the framework clear?

What are the issues you foresee?

How do we create buy-in within our networks?
