Ocelot checks whether any changes made by user conflict with changes that may have been saved recently by others 2. No conflicts found => save to Oracle Saves to current organism KB Unsaved KB indicator (*) Ocelot Concurrency Control III SRI International Bioinformatics Revert KB operation Refresh KB operation automatically at 2:00 am if the user does not have any unsaved updates in their wokspace Constraint Checking SRI International Bioinformatics General rules that constrain the valid relationships among instances Constraints are checked when new facts are asserted to assure that the KB remains logically consistent Constraints on slots: Domain violation checks to make sure they should be in instances of that class Range violation : value type value cardinality Inverse Cardinality Lisp-predicate Consistency Checking SRI International Bioinformatics Removes newlines from names Converts < to | in string citations Check isozyme sequence similarity Fix references from polypeptides to genes Changes compound names to ids in a variety of slots Matches physiological regulators to other regulators Cross-references compounds to reactions Checks pathways predecessors/reactions/subs Check reactions Check compound structures Calculates sub- and super-pathways Finds missing sub-pathways links Verifies chromosome components and positions
