Jdownloader provides a container API for webmaster to create DLC, RSDF and CCF files, which is now available in version 0.72.
The last days, there were a few problems, so we strongly advise all webmasters to update to DLCAPI v0.7. The table's structure for dlc-key-pair-cache changed. Moreover we advise you to enter your emailadress in the configs. This helps us to contact you in case of any problems.
