Internet publishers have devised a complicated new system called the Automated Content Access Protocol (ACAP) that aims to supplement the aging Robots Exclusion Protocol by providing a means for site operators to provide more detailed instructions to web spiders and indexing programs. Although there are contexts in which a richer and more expressive mechanism for establishing indexing parameters would be advantageous for site operators, ACAP goes far beyond indexing and attempts to dictate the terms under which content can be used and displayed. ACAP, which is being devised by a cabal of publishing companies with very little regard for implementation challenges, would likely represent a significant burden for major search engines—assuming that any decide to support the protocol.
