Proposal
• Post-DRM standardisation difficulties (e.g. ISO/IEC or W3C)
• Web open and heterogeneous
• Business models beyond copy and distribute
• DRM just about access control, Copyright is much more complex
• Requires higher level of abstraction (not bits or pixels)
• Concentrate on the concepts, not how they are expressed
formalise meaning  SEMANTICS

Creation lifecycle
• Sample: broadcast of a serial adapted from a literary work
• A creator adapts the original literary work Victor Hugo’s “Les Miserables”, to
produce a serial. The resulting adaptation to a serial is realised as a script that
is performed by some actors, including Gerard Depardieu, and recorded into
a motion picture. This motion picture is finally broadcasted to users who can
tune the resulting communication.
Creation lifecycle
• Sample: webcast of a composition recording
• A composer writes down a music sheet for her new composition, which is
published as sheet prints. Moreover, it is played in a studio to record
a master which is later made available as a webcast.
IFLA's FRBR Creation Model
• International Federation of Library Associations and Institutions (IFLA)
Functional Requirements for Bibliographic Records (FRBR)
• Most commonly referenced creation model
• Work: abstract entity; no material object. Recognised through its realisations
or expressions
• Expression: the intellectual or artistic realisation of a Work
• In the form of alpha-numeric, musical, or choreographic notation, sound, image, object,
movement, etc., or any combination of such forms
• Manifestation: the physical embodiment of an Expression of a Work
• Manuscripts, books, periodicals, maps, posters, sound recordings, films,...
• Item: a single exemplar of a Manifestation
• Enables us to identify individual copies of a Manifestation separately

Blockchain Can Legally Authenticate Evidence, Chinese Judge Rules
• A court in China's Hangzhou city has ruled that evidence authenticated with blockchain technology can be
presented in legal disputes. The judge commented:
• "The court thinks it should maintain an open and neutral stance on using blockchain to analyze individual
cases. We can't exclude it just because it's a complex technology. Nor can we lower the standard just
because it is tamper-proof and traceable. ... In this case, the usage of a third-party blockchain platform that
is reliable without conflict of interests provides the legal ground for proving the intellectual infringement."
• According to data from the court, the case was filed in January by Huatai Yimei, a Hangzhou-based media
company, against a Shenzhen-based technology firm for copyright infringement.
• During the legal procedure, the plaintiff showed screen-captured images of web pages and text that it
considered unauthorized usage by the Shenzhen company. Previously, Huatai Yimei had encoded the
images, website sources codes and other evidence through a third-party site named baoquan.com – a
blockchain-based evidence deposition platform – and attempted to use that evidence in the proceedings.
• Even if the disputed media assets should be taken down at a later stage, the court decided that evidence
stored on the blockchain is sufficient to be legally accepted by the court. As such, the judge ruled in favor of
the plaintiff.
• The decision marks one of the first officially sanctioned use cases for blockchain in legal proceedings.

Baidu Launches Blockchain-Based Image Rights Protection Platform
• Chinese internet search giant Baidu has launched a digital image property rights management
platform based on Blockchain, the company announced Wednesday, April 11.
• The service, called Totem, timestamps each submitted original image with a real-time identity
and other user data, storing it on a traceable and immutable Blockchain.
• According to the Baidu’s announcement, the company’s existing artificial intelligence capacities –
including image analysis and semantic understanding – will feed into the construction of unique
image tags, with the underlying Blockchain system allowing circulating images to be traced,
reproduced, and monitored in order to substantiate or refute allegations of copyright
infringement.
• Baidu announced that traditional stock photo services – including Getty Images partner, Visual
China Group – have already moved onto the platform.
• Baidu’s Totem comes hot on the trail of Kodak’s own image rights management Blockchain
platform, announced in Jan. 2018. It similarly uses a digital ledger to establish rights ownership,
and also offers a KODAKCoin token for the online photo community to pay for and receive
dividends on their image licenses.

The resulting adaptation to a serial is realised as a script that is performed by some actors, including Gerard Depardieu, and recorded into a motion picture. This motion picture is finally broadcasted to users who can tune the resulting communication.

    Blockchain Can LegallyAuthenticate Evidence, Chinese Judge Rules • A court in China's Hangzhou city has ruled that evidence authenticated with blockchain technology can be presented in legal disputes. The judge commented: • "The court thinks it should maintain an open and neutral stance on using blockchain to analyze individual cases. We can't exclude it just because it's a complex technology. Nor can we lower the standard just because it is tamper-proof and traceable. ... In this case, the usage of a third-party blockchain platform that is reliable without conflict of interests provides the legal ground for proving the intellectual infringement." • According to data from the court, the case was filed in January by Huatai Yimei, a Hangzhou-based media company, against a Shenzhen-based technology firm for copyright infringement. • During the legal procedure, the plaintiff showed screen-captured images of web pages and text that it considered unauthorized usage by the Shenzhen company. Previously, Huatai Yimei had encoded the images, website sources codes and other evidence through a third-party site named baoquan.com – a blockchain-based evidence deposition platform – and attempted to use that evidence in the proceedings. • Even if the disputed media assets should be taken down at a later stage, the court decided that evidence stored on the blockchain is sufficient to be legally accepted by the court. As such, the judge ruled in favor of the plaintiff. • The decision marks one of the first officially sanctioned use cases for blockchain in legal proceedings.

    Baidu Launches Blockchain-BasedImage Rights Protection Platform • Chinese internet search giant Baidu has launched a digital image property rights management platform based on Blockchain, the company announced Wednesday, April 11. • The service, called Totem, timestamps each submitted original image with a real-time identity and other user data, storing it on a traceable and immutable Blockchain. • According to the Baidu’s announcement, the company’s existing artificial intelligence capacities – including image analysis and semantic understanding – will feed into the construction of unique image tags, with the underlying Blockchain system allowing circulating images to be traced, reproduced, and monitored in order to substantiate or refute allegations of copyright infringement. • Baidu announced that traditional stock photo services – including Getty Images partner, Visual China Group – have already moved onto the platform. • Baidu’s Totem comes hot on the trail of Kodak’s own image rights management Blockchain platform, announced in Jan. 2018. It similarly uses a digital ledger to establish rights ownership, and also offers a KODAKCoin token for the online photo community to pay for and receive dividends on their image licenses.
