EN 17650 – The new standard for digital preservation of cinematographic works

EN 17650 is a proposed new European Standard for the digital preservation of cinematographic works. It allows organizing of content in a systematic way, the so called Cinema Preservation Package (CPP). The standard defines methods to store content in physical and logical structures and describes relationships and metadata for its components. The CPP uses existing XML schemes, in particular METS, EBUCore and PREMIS to store structural, descriptive, technical and provenance metadata. METS XML files with their core metadata contain physical and logical structures of the content, hash values and UUIDs to ensure data integrity and links to external metadata files to enrich the content with additional information. The content itself is stored based on existing public and industry standards, avoiding unnecessary conversion steps. The paper explains the concepts behind the new standard and specifies the usage and combinations of existing schemes with newly introduced metadata parameters.

In the Circle of Sense and Nonsense: Through a Mathematical Model of Meaning

The terms sense and nonsense indicate important phenomena in social environment. In this paper, we explore the relations and interactions between sense and nonsense with the following three-fold goal: 1. Elaborations of the formal definitions of these concepts. 2. Investigation of the processes of making sense from nonsense. 3. Establishment of the mathematical foundations for a sense-nonsense theory. On this way, we extend the dyad sense-nonsense by introducing the concept no-sense situated between sense and nonsense and by extending the concept sense to the concept poly-sense. In addition, we construct a mathematical model of these concepts and related processes using logical structures such as logical calculus, logical variety and logical prevariety. This approach correlates with the opinion of Leonardo da Vinci who wrote “No human investigation can claim to be scientific if it doesn't pass the test of mathematical proof.”

System of Logical Structures in Natural Science-Oriented Curriculum and its Effect on Teaching

The system of logical structures in natural science- (biologically-, ecologically- and physics-) oriented curriculum is defined as a set of features, which depict the main ideas of a certain topic. Basically, it is a unique model presenting the topic´s key points. Graphical representation of the curriculum logical structure can be provided (implemented) as: a) traditional printed graphic form b) computer (virtual) form. When visualizing the logical structure system of natural science curriculum (including biologically-, ecologically- and physics-oriented school subjects), we mainly use the following structural components: Word maps, Applets, Orientation graphs (transport diagrams), Development diagrams, Venn diagrams, Structurograms, Sequence diagrams and others. This research paper includes a pedagogical experiment to verify the effectiveness of teaching with the use of graphic visualization of the curriculum logical structure.

Contextualizing Sustainable Development Metric Standards: Imagining New Entrepreneurial Possibilities

Imagination is more important than knowledge, but if intellect does not provide the needed logical structures, capacities for envisioning new possibilities are overly constrained. The sustainability problems we face today cannot be solved with the same kind of thinking that created them, but clarity on what counts as a new kind of thinking is sorely lacking. This article proposes methodical, model-based ways of heeding Bateson’s warning about the negative consequences for the ecology of mind that follow from ignoring the contexts of relationships. Informed by S. L. Star’s sense of boundary objects, a sequence of increasingly complex logical types distinguishes and interconnects qualitatively different kinds of thinking in ways that liberate imaginative new possibilities for life. The economy of thought instantiated at each level of complexity is only as meaningful, useful, beautiful, ethical, and efficient as the standards informing local adaptive improvisations. Standards mediating the general and specific, global and local, universally transcendent and embodied particulars enable meaningful negotiations, agreements, and communications. Attending to the differences between levels of discourse sets up new possibilities for creative and imaginative entrepreneurial approaches to viable, feasible, and desirable goals for measuring and managing sustainable development.
