Originally intended as a filter to enable parents to prevent their children accessing unsuitable Web material, PICS is potentially a key architectural component for various Web developments, including storing digital signatures. Now, information managers are less happy, looking after large collections of documents is difficult. Brian recommended that metadata should, as far as possible be centrally controlled, so that changes to large numbers of documents can be made much more easily. New tools to effect this efficient meta-management are needed. It aims to tackle the problems of web searching, too many resources and no quality control, by providing software for subject experts to build collections of high quality resources.
