WHAT IS OPEN CULTUUR DATA?

Open Cultuur Data is a network of professionals from the cultural industries, developers, designers, IPR-experts and open data experts. It opens up cultural data en stimulates de development of new applications.

By doing so culture in the broadest sense is made accessible for a larger audience.

Open Cultuur Data is initiated by Open State Foundation, Kennisland and the Netherlands Institute for Sound and

Vision.

HOW?

Open Cultuur Data supports the cultural heritage sector in the release of culture data in the following way:•encourage making more open culture data available•collecting  and disseminating  open culture  data via an  open digital  infrastructure•collecting and sharing knowledge and experience with open culture data through masterclass•encouraging the making of new applications based on open culture data through a competition (e.g. Wiggle)

CHALLENGE OF MEASURING IMPACT

• Evidence (statistical) for the value that is created based on open data is still rare (especially in the GLAM domain) and predominantly anecdotal.

• Often difficult for institutions to differentiate between their online collections in general and the parts that are open.

• By its very nature, open data/content can be distributed without limits, through many different channels making its usage inherently hard to track and trace.

IMPORTANCE OF MEASURING IMPACT

• Report to higher management• Increase the allocation of resources towards

opening up data• Compare and evaluate ‘content-strategies’

IMPORTANCE OF entral data collection

• Wikimedia chapter can set targets• USP’s of cooperation become clearer• Comparable results

METHODS FOR MEAsuRING IMPACT

• Tools– Baglama: • Pagevisits • No. of pages containing items

– Glamorous: • Use on Wikipedia and other Wikimedia projects • No. of items used in pages

Which data?

• Total pagerequests• Monthly pagerequests• Months tracked• No. of items• Distinct items used• Times used

METHODS FOR MEAsuRING IMPACT

REUSE: What are we talking about?

THE DATA

• Data as far back as 2010• Data from 24 Dutch institutions, a total of 27

collections, traced as categories on Wikimedia Commons.

• Structurally measured since Nov. 2014

RESULTS - general

• Total of almost 1.8 billion measured pagerequests!

• Almost 60 million monthly visits

• 580.000 items available (2% of total)

• 76.000 (13%) items used• Used 100.000 times• On average 27% of

category used

RESULTS - general

• Total of 141 monthly pagerequests for each uploaded file

• Total of 2160 pagerequests for each unique item used in one or more articles

RESULTS - general

RESULTS - Specifics

• High scores– Nationaal Archief– Rijksmuseum– Tropenmuseum– Beeld en Geluid

• Large quantity of reused items is no guarantee for many pagerequests:

Reused items

Pagerequests

Peace Palace Library

103 708.405

Amsterdam Museum

1.128 686.739

RCE 11.272 1.125.254

Tropenmuseum 11.191 7.507.401

RESULTS - general

RESULTS - Specifics

• From December 2014 until February 2015 reuse increased by 3.4%

• Items in some collections get used as many as four times on average. (e.g. Beeld en Geluid Wiki and Anefo, both containing portraits of famous people).

Challenging collections

A.B. Wigman, 1931. CC-BY-SA Collection Gemeentearchief Ede

Abraham Bloemaert, 1619. Collection University Library Nijmegen

Anselmus van Hille, Hommes Illustrés, 1717. Collection Peace Palace Library

Interpretation of results

• Which data we can still get:– Types of content (age, subject matter, quality, etc.)– Number of events organized to stimulate reuse– Data for just the Netherlands

• Which data we would like to get:– Number of human visits– Bounce rate– Mediaview statistics
