The concept of metadata has gained popularity. Creation of videos and photography make use of metadata. It is also used in web pages and in a library to archive information. The metadata must always meet worldwide standards. Metadata is well structured using established schemes like models and standards of metadata. It has three categories.
They include descriptive, structural, and administrative type of metadata. Metadata mean different things. Some say it is a device that understands information while others use it as a record. Main uses include data recovery, framework of electronic resources and digital documents.
Metadata is also used in the extraction and maintenance of information. 99% of the information is digitally created while only 0.1% is written on the paper. About seventy percent of the created data is never printed and, only 20% may be printed. This has seen metadata gaining popularity.
The term metadata simply refers to any amount of information providing in depth information on one material or other multiple. It provides insight on the ways of creating data, the reasons for the data and the date of creation.
It also captures the data author, where on network the data is and standards which were used. The concept of metadata applies to electronically stored data and its use. It describes the structure, meaning and how the files are administered. Its main rationale is to make it effortless to repossess, handle or use as a resource. The web page usually displays metadata in Meta tags form (NICO, 2004).
Metadata can be related to some discussions I experienced. The discussion was about state of art in Sub-Saharan Africa. Internet acted as a major source of information to the discussion. The United Nations website and other principal sources provided detailed information on the topic. Several sites gave insight to every situation under discussion. There were linkages to other websites with detailed information, which made the discussion easier than books.
The sites spelled out clearly the dates of publications and places of publications. Some websites required authentication. An article was written after the discussion. It came out with information art in Sub-Saharan Africa to back up other previous findings. The report contained the list of participants. It spelled out the place of discussion and soft copies given to the relevant authorities. A copy will be posted on the Internet.
A good example of metadata is an image. It may comprise of metadata which specifies its size. The size may include side dimensions and units of measurements. The color aspect may also be depicted. This may entail contrast, colors used and the extent of the colors. Metadata specifies the resolution of the image.
The date of creation and who created the image are also shown in the metadata. Related information like the links to the image and where it is found in the metadata.
Electronic discovery is cheaper than the discovery of paper-based information. Large corporations and societies and states have an easy time going through the information.
This has increased overall production. The Collection, storage and evaluation of information act as evidence (Michele & Nimsger, 2009). It has improved academics and made work easier than before. Metadata has improved the photography and video sector. The rules and regulations that govern metadata prevent piracy and preserve the integrity of the author. Any information required is just a click away in the digital world.
