The Complexity of Querying Indefinite Data about Linearly Ordered Domains (Preliminary Version)

Summary: Complexity analysis of positive-existential queries over databases with indefinite order information (partial orders interpreted via all linear extensions under open-world semantics with special nulls). Proves high hardness (Pi^p_2-complete containment; often intractable data complexity) and isolates PTIME fragments (monadic queries; some disjunctive cases via well-quasi-order arguments).
