Digital Curation
Digital curation is the selection, preservation, maintenance, collection and archiving of digital assets. Digital curation establishes, maintains and adds value to repositories of digital data for present and future use. This is often accomplished by archivists, librarians, scientists, historians, and scholars. Enterprises are starting to use digital curation to improve the quality of information and data within their operational and strategic processes. Successful digital curation will mitigate digital obsolescence, keeping the information accessible to users indefinitely. Digital curation includes digital asset management, data curation, digital preservation, and electronic records management. Word History Much like the word ''archive'' has layered meanings and uses, the word ''curation'' is both a noun and a verb used originally in the field of museology to represent a wide range of activities, most often associated with collection care, long-term preservation, and exhibition ...

A List Apart
''A List Apart'' is a webzine that explores the design, development, and meaning of web content, with a special focus on web standards and best practices. History ''A List Apart'' began in 1997 as a mailing list for web designers, moderated and published by Jeffrey Zeldman and Brian Platz. Founder's notes, by Zeldman: In 1997, web developer Brian M. Platz and I started the A List Apart mailing list because we found the web design mailing lists that were already out there to be too contentious, too careerist, or too scattershot. There was too much noise, too little signal. We figured, if we created something we liked better, maybe other people would like it too. Within months, 16,000 designers, developers, and content specialists had joined our list. Editing was the key. Many members submitted comments and topics each day; we dumped the dross, published the gold, often selecting pieces for their thematic relevance to one another. Through editorial cultivation, we rapidly grew a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. ...

Hologram
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other Holography#Applications, applications. In principle, it is possible to make a hologram for any type of Holography#Non-optical holography, wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be Computer-generated holography, computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest. Overview and ...
