...highlighting two examples
• Open Images (openimages.eu)
• emphasis: sharing content and data
• Europeana (europeana.eu)
• example of linked open data
Open, open, open!•Open source (MMBase, FFmpeg, LAMP)•Open media formats (Ogg Theora, WebM)•Open standards (HTML5) •Open API (OAI-PMH)•Open content!
Open content•Creative Commons – BY-SA as recommended
license•3000 items from the Sound and Vision collection•Work with other providers too•Low resolution vs. high resolution

Conclusions• Time to embrace openness: innovation, impact, reuse
• New success metrics needed:
• Income: measured in money (low/high res)
• Public Outreach: to measure the number of (online) visitors
• Reuse: to measure the use of data and content by heritage institutions themselves and by others
• Public Participation: to measure the added metadata and content
• Collaboration (Open Culture Data) helps to built momentum and raise awareness
• Linked Open Data gaining momentum in the CH domain
