Integration of China Relics and gLite with gLibrary Background China and Italy have very rich resources of cultural heritage and historical relics. Both sides have collaborated on many fields. Shaanxi is one of the most important regions of the birth and development of Chinese Civilization. –The most glorious dynasties capitals were founded in Shaanxi.

Integration of China Relics and gLite with gLibrary Why on Grid? Grid represents Resource sharing and Massive storage Grid allows to securely save millions of files distributed on several storage sites Each file can be replicated on different sites INFN has developed gLibrary to easily manage digital data on gLite based grid infrastructures We can apply this platform to store and distribute cultural heritage and historical relics of China Beijing, EPIKH Workshop,

Integration of China Relics and gLite with gLibrary Data Management SE(Storage Element) is where data actually are stored All SEs support GSIFTP(Grid Security Infrastructure File Transfer Protocol) We use this way to transfer files from UI(User Interface) to SE For example: –globus-url-copy file:/home/zhlinl/relic/hunting.jpg gsiftp://eunode4.jsi.buaa.edu.cn/dpm/jsi.buaa.edu.cn/home/euchina/relicrep/ima ge/hunting.jpg Beijing, EPIKH Workshop,

Integration of China Relics and gLite with gLibrary Metadata Management What is metadata? –data about data –defined to provide information and one or more aspects of the data Why need metadata? –For files stored on grid sites, users need an efficient method to  describe the files  locate files based on their information –Users can assign several descriptive attributes to the files –System responds the user’s request based on these attributes We use AMGA to manage metadata Beijing, EPIKH Workshop,

Integration of China Relics and gLite with gLibrary Metadata Management Metadata basic concept –Entries –real objects that we need assign metadata to –Attribute – description information of an entry  Name --name of the attribute  Type --type of the attribute (int, float, string,….)  Value –value of an entry’s attribute –Schema – a set of attributes –Metadata – a list of attributes, including Name, Type, and Value –Collection – a set of entries with a schema Beijing, EPIKH Workshop,

Integration of China Relics and gLite with gLibrary Metadata Management An example: murals 10 Beijing, EPIKH Workshop, Attributes Entries Schema

Integration of China Relics and gLite with gLibrary Metadata Management unwise to upload all the metadata manually, especially for enormous number of files Java APIs –can be used on any platform(Windows, Linux, Mac OS, ….) –automatically upload all the metadata to AMGA Beijing, EPIKH Workshop, Just One Click!
