No for now. Currently SHARE is utilized to create and distribute CDISC standards. Companies interested in extending the CDISC standards should subscribe to SHARE content, load that content into their own metadata repository instance, and then extend the standards as needed to include study level content.
Many companies have shared their desire to post their custom content to SHARE. This represents a substantial investment in SHARE technology enhancements, processes and new teams to review and curate the content to ensure high quality and consistency in the metadata repository. Substantial additional community discussion and new sources of support would be required to fulfill these requirements.
