Even if bandwidth limitations are very large, these file transfer methods require that the data is centrally stored, making the data inaccessible if the server malfunctions.įigure 1. Unfortunately, as the number of requests for data increases and the provider's bandwidth becomes saturated, the access time for each data request can increase rapidly. In addition, the server of the data has to have a large amount of bandwidth to provide adequate download speeds for all data requests. These protocols require that a single server be the source of the data and that all requests for data be handled from that single location ( Fig. However, the practical aspect of moving data from one location to another has relatively stayed the same that being the use of Hypertext Transfer Protocol (HTTP) or File Transfer Protocol (FTP). ![]() Considerable effort and attention has been given to improving the portability of data by developing data format standards, minimal information for experiment reporting –, data sharing polices, and data management –. In parallel, and also at an increasing rate, is the demand to make this data openly available to other researchers, both pre-publication and post-publication. ![]() The amount of data being produced in the sciences continues to expand at a tremendous rate.
