abstract = {We describe how a collection of documents expressed in {XML}-conforming
languages such as {CML} and {XHTML} can be authenticated and validated
against digital signatures which make use of established {X}.509
certificate technology. {T}hese can be associated either with specific
nodes in the {XML} document or with the entire document. {W}e illustrate
this with two examples. {A}n entire journal article expressed in
{XML} has its individual components digitally signed by separate
authors, and the collection is placed in an envelope and again signed.
{T}he second example involves using a software robot agent to acquire
a collection of documents from a specified {URL}, to perform various
operations and transformations on the content, including expressing
molecules in {CML}, and to automatically sign the various components
and deposit the result in a repository. {W}e argue that these operations
can used as components for building what we term an authenticated
and semantic chemical web of trust.},
