SIDB archives 2-D, 3-D images, time series or any kind of file. Image files are stored unchanged in a central directory (archive). Users of the system are subdivided in groups, and whoever owns an image (by uploading it) can determine who else on the system is allowed to view and use the image. Files can be uploaded through HTML, or using a mounted (smb, NFS, etc..) drive. Entering meta-data is facilitated by user-definable templates. The meta-data fields currently in use have been designed for images obtained by (fluorescence) microscopy. When combined with cheap, large hard drives and a fail-save backup mechanism, SIDB provides a perfect means to archive images within the setting of small to medium-sized research groups. However, it might be of use wherever people collaborate on images.
