What is metadata repository?
Metadat storage is a database. Specifically, it is a database that stores data on other data. The website uses metadata to provide descriptions about the types of data they contain. Metadata can contain things such as browsers agents (Mozilla Firefox or Internet Explorer) as well as other information that describes the items on the page.
Metadat storage is a way to ensure the consistency of metadata. Allowing this data is stored in the database and referenced to the applications or pages that require it, keeping the data consistent. If metadata is referred to as need, from the metadata storage, the storage space used to store these website data descriptions will also be smaller. Because no single ADATA is not met, information is not used much across companies. As technology grows and more Internet organizations will find the need for these huge amounts of data about data, there will probably be an attempt to centralize the data contained in metadata storage.
metadata varies across platforms, devices and applications. Devices such as iPod contain data and video data. Metadata for data stored in the device would be things like an artist's name, album name and tracking information. Using software by a device user and adding or editing metadata any song or video at any time. Digital cameras also record metadata about photographs they take, such as image size, camera type, date and time information, and other details. A website like Flickr can read this information from photos recorded to their servers and enable users to users for images taken by a certain camera type or in a certain format.
Microsoft Windows also stores metadata for things like Word documents. Data is easier to edit or access from Windows Vista than in previous versions of Windows, but data is stored for each file, such as the author's name, access date, date, file size and much more information. Windows will not require a user or file creator to fill many items that he is able to collect. Some things are only filled if the user wishes them to fill, others are recorded when there are certain actions - they make them invisible to users.
Global metadata storage is probably somewhere in the future and there will be some who do not want to share this information, but most of them are used by services that grow every day in popularity and sharing this information is only to improve these services.
