Open source development is a trend that has proven to be successful and makes specification contributions easier and more efficient. ONVIF schema files and related documents are accessible on GitHub. Anyone may copy and distribute the files, make/propose changes to copies of the files and submit the change requests to ONVIF. Once proposed changes are accepted/approved by the ONVIF Technical Committee, GitHub automatically merges the changes to a development branch. This eliminates the need for a dedicated editor to update network interface specification files. And once clearance is achieved following an IPR review, the new development branch is integrated into the master file. Enabling development on GitHub eliminates manual handling of change requests currently done through a ticket system. ONVIF moved from Word-based documentation to DocBook for easy maintenance and merging of specifications.
