The HST Cache: Metadata and Services

We present new developments of the HST Cache that are related to the greatly improved metadata now available within the system. This work includes the interface to CAOM, new SSAP and SIAP VO services, the integration of HLA images produced at CADC and STScI into the HST Cache metadata tables as well as work on improved user interfaces. Somewhat more operational details are given by Haase J. et al. 2010 in this volume.
