[Verse 1]
In the world of rules and data flow
Where logic meets the web we know
There's XML that speaks in tongues
Called RuleML where structure's sung
It marks up rules for minds to read
Semantic webs fulfill the need
[Chorus]
Rule M L, Rule M L
XML for rules that tell
S W R L takes it higher
Horn clauses set the web on fire
When systems store and data calls
These languages will build the walls
[Verse 2]
Now SWRL takes a bigger stand
Combines the best from different lands
OWL ontologies hold the truth
While RuleML provides the proof
Horn clause rules that reason well
With logic engines they compel
[Chorus]
Rule M L, Rule M L
XML for rules that tell
S W R L takes it higher
Horn clauses set the web on fire
When systems store and data calls
These languages will build the walls
[Bridge]
System stores some data there
If confidential, then beware
Arrow points to what must be
A-E-S encryption, two-five-six the key
Variables flow with question marks
Logic reasoning leaves its marks
[Verse 3]
Management controls need structure tight
Rules that fire when conditions bite
If system holds confidential gold
Then encryption must take hold
Description logic reasoners see
What requirements need to be
[Chorus]
Rule M L, Rule M L
XML for rules that tell
S W R L takes it higher
Horn clauses set the web on fire
When systems store and data calls
These languages will build the walls
[Outro]
From markup tags to reasoning chains
Semantic rules in web domains
RuleML and SWRL combined
Control the future, rule by design
