Cultural Heritage (CH) data is syntactically and semantically heterogeneous, multilingual, semantically rich, and highly interlinked. It is produced in a distributed, open fashion by museums, libraries, archives, and media organizations, as well as individual persons. Managing publication of such richness and variety of content on the Web, and at the same time supporting distributed, interoperable content creation processes, poses challenges where traditional publication approaches need to be re-thought. Application of the principles and technologies of Linked Data and the Semantic Web is a new, promising approach to address these problems. This development is leading to the creation of large national and international CH portals, such as Europeana, to large open data repositories, such as the Linked Open Data Cloud, and massive publications of linked library data in the U.S., Europe, and Asia. Cultural Heritage has become one of the most successful application domains of Linked Data nd Semantic Web technologies. This book gives an overview on why, when, and how Linked (Open) Data and Semantic Web technologies can be employed in practice in publishing CH collections and other content on the Web. The text first motivates and presents a general semantic portal model and publishing framework as a solution approach to distributed semantic content creation, based on an ontology infrastructure. On the Semantic Web, such an infrastructure includes shared metadata models, ontologies, and logical reasoning, and is supported by shared ontology and other Web services alleviating the use of the new technology and linked data in legacy cataloging systems. The goal of all this is to provide layman users and researchers with new, more intelligent and usable Web applications that can be utilized by other Web applications, too, via well-defined Application Programming Interfaces (API). At the same time, it is possible to provide publishing organizations with more cost-efficient so utions for content creation and publication. This book is targeted to computer scientists, museum curators, librarians, archivists, and other CH professionals interested in Linked Data and CH applications on the Semantic Web. The text is focused on practice and applications, making it suitable to students, researchers, and practitioners developing Web services and applications of CH, as well as to CH managers willing to understand the technical issues and challenges involved in linked data publication.

Publishing and Using Cultural Heritage Linked Data on the Semantic Web

LED arrays and light fixtures are disclosed wherein the discrete LEDs in the array emit light at one of multiple dominant wavelengths corresponding to at least five different colors within the visible spectrum. Systems based on the LED arrays and light fixtures are also disclosed. Additionally, a method of testing human visual perception is also disclosed.

LED lighting arrays, fixtures and systems and method for determining human color perception

A combination mirror and media display device assembly is provided. The combination mirror and media display device includes a mirror platform having a media display device viewing area and a media display device coupled to the mirror platform. The media display device is positioned to display images through the media display device viewing area.

Back lit mirror with media display device

A filter in the form of a lens or panel or a sleeve for a fluorescent light source made with pigments therein that will modify the fluorescent output to resemble daylight. An ultraviolet absorber is also included in the panel.

Full spectrum filtering for fluorescent lighting

Backlit mirror with TV

An electric make-up mirror having light sources which provide substantially uniform energy output through most of the visible region, which when used in conjunction with light filters will simulate specific lighting conditions such as daylight, office light (fluorescent), home light and evening light (incandescent). The light sources are comprised of special lamps which provide a unique degree of flexibility in that various lighting conditions may be simulated with a minimal loss of energy. The mirror is provided with two matching light sources, and two matching filter assemblies disposed on opposite sides of the mirror. The filter assemblies are adjusted by a single control mounted for the synchronous selection of a matching filter from each of the filter assemblies. The light filters of each filter assembly, when interposed between the light sources and the user, selectively vary the spectral energy distribution of the light transmitted from the light sources so as to simulate daylight, ordinary fluorescent light and incandescent light. The mirror allows the user to select the illumination approximating the type of light under which the user expects to be seen.
