Abstract: A computer-implemented method for preflighting of electronic documents containing content intended for web publication is described together with an integrated system for performing the preflighting checks and managing the workflows associated with web publication of content. The method allows the web publisher to predefine rules for the preflighting checks in accordance with its technical specifications for web publication and also personalize the rules according to the sender of the document. Rules may be defined and applied to content indirectly incorporated by embedded links to third party hosted web sites. The system provides for a high degree of flexibility in the way the rules may be specified and implemented and also allows for the use of other reference identifiers, which provide a separate channel by which booking and reconciliation functionality may be achieved associated for any given publication of content.
