To ensure the compatibility of separately developed systems for working with DELPH-IN-produced resources, we should formalize the formats of files and structures used by multiple systems.

Goals

• Provide a BNF representation of the syntax for each structure
• Provide an interpretation of fields, values, etc.
• Small Test set for implementers to test against
• "Official" implementations follow the specifications rather than the other way around
• Documentation for future delphinistas

Structures and Representations

[incr tsdb()]

• profiles (relations, results, etc; see ItsdbReference)

• ItsdbDerivations

MRS

• Simple MRS
• Indexed MRS
• XML Later...
• RMRS
• DMRS

PET

• PetInput

Discussion

SEM-I

• A wellformed mrs normally has information about types, information from the grammar

• It is desirable that the hierarchy among mrsitems and predicates get to stand in hierarchical relation - different from in the grammar

• Semantic hierarchy and grammar hierarchy are separate. For example: person-number is conflated as single property in the grammar, MRSs dont

• How many grammars have a semi? ERG and NorSource. Jacy has an input to the transfer machinery.

• Can a type hierarchy be shared between the grammar and the SEM-I? May be incompatible in principle.

• One shouldn't need a grammar loaded to do MRS manipulation.

• Building two hierarchies in parallel is a little duplication of effort

Documentation

The best action is to set up a page let people add info, mark it as proposal/draft, and request for comments
