IP Considerations for Blockchain Technology

Nelson Rosario

If you are new to Blockchain, this intro will guide you through the main concepts, use cases and technologies behind it. Blockchain is a revolution that goes beyond Bitcoins. It will involve the relationships between normal people and governments or established power, other than the way most of the the applications we use today works. Consider this an effective Blockchain guide for newcomers. These slides have been developed and used in an Open Lesson at the Geeks Academy.

The City of Vienna sees tremendous opportunities for the future of the administrative administration in the currently much discussed Blockchain technology. Transparency, openness and participation are the leading motifs for our thoughts and actions concerning the digitization of the city. These so-called ‚Viennese principles‘ are supported by the use of blockchain technology. The City of Vienna has therefore decided to actively use blockchain technology for the first time.

CIDOC CRM+FRBRoo: an Integrated View of Museum and Library Information

Patrick Le Boeuf

Bibliothèques et musées sont des institutions de mémoire, ce qui les rapproche, mais ces institutions ont également des spécificités qui les distinguent : les collections muséales consistent essentiellement en objets uniques, tandis que les bibliothèques mettent l'accent sur la notion plus abstraite de publications dont de multiples établissements, voire un seul et même établissement, peuvent posséder des exemplaires réputés "identiques". Néanmoins, il y a suffisamment de points communs entre ces deux catégories d'institutions patrimoniales pour qu'il vaille la peine d'assurer l'interopérabilité des descriptions qu'elles produisent de leurs collections. Historiquement, toutefois, bibliothèques et musées ont d'abord développé séparément leurs propres modèles conceptuels, pour ne les faire converger qu'à partir de 2003. L'intervention présente les grands principes qui ont présidé au développement du CIDOC CRM, modèle conceptuel de l'information muséologique, et de FRBROO, extension du CIDOC CRM qui reformule le modèle FRBR de l'information bibliographique, et donne un très rapide tour d'horizon de quelques utilisations concrètes de ces deux modèles dans le domaine des humanités numériques.
