Quote: for any two data structures there is a largest common substructure, at worse, the bit; useful for communication [»hehnEC3_1983]

Quote: MIT's Common system for data type conversion [»giffDK7_1985, OK]

Quote: an external data format should be self-describing and preserved under round-tripping; e.g., Lisp S-expressions [»simeJ1_2003]

Quote: Kleisli's data exchange format is CPL values; self-describing, e.g., {| indicates a bag; no fixed schema or type declaration [»wongL9_2000]

Quote: describe data with a declarative language; it is robust, concise, and self-documenting; generates a parser, validator, printer, profiler, formatting tools, query support, etc. [»fishK6_2005]

Quote: Kleisli and its self-describing data exchange use parametric polymorphism and type inference; from functional programming [»wongL9_2000]

Quote: all types may be inferred in CPL; allows any data source to be used as long as the inferred type and actual structure are compatible [»wongL9_2000]

Quote: type erasure is the inverse of validation; validation if and only if value matches type and erases to the untyped value [»simeJ1_2003]

Quote: XML cannot distinguish integers from strings; XML Schema requires all type extensions before validation [»simeJ1_2003]

Quote: built a prototype translator from a standard markup form into an internal format [»mamrSA5_1987]

Quote: little work in automatic translation systems; should support both construction and use of translation software [»mamrSA5_1987]

Quote: define translations in both directions by an attribute grammar [»mamrSA5_1987]

Quote: Generalized Markup Language, GML, does not restrict documents to an application, formatting style, or processing system [»goldCF6_1981]

Quote: MUCH imports SGML documents, builds text blocks, makes nodes of section headers, and links nodes by the table of contents [»radaR3_1993]

Quote: translates from Standard Generalized Markup Language; widely used [»mamrSA5_1987]

Quote: automatic translation is practical if groups share a specialization hierarchy; helps preserve the meaning of messages [»leeJ1_1990]

Quote: translate between partially shared object types: automatic adoption, type translation, translation to supertype [»leeJ1_1990]

Quote: want to translate between type hierarchies for semi-structured messages; preserve meaning while allowing autonomy for different groups [»leeJ3_1988]

Quote: a heterogeneous database may need a common view despite different definitions, algorithms, and units; users can specify the mappings [»ahmeR12_1991]

Quote: a Pegasus schema makes a local data source appear as Pegasus database; maps between data models and query languages [»ahmeR12_1991]

Quote: classified the types of structural and representational discrepancies in multidatabase systems; basis for UniSQL/M [»kimW12_1991]

Quote: schema conflicts occur when the same information uses different structures, names, data types, or constraints [»kimW12_1991]

Quote: if translate between type hierarchies for semi-structured messages, need to notify other groups of changes [»leeJ3_1988]

Quote: PODUS uses interprocedures to change procedure interfaces and mapper procedures to change data formats [»segaME3_1993]

Quote: a thunk stores the address of a parameter into a known location for calling a procedure [»ingePZ1_1961]

Quote: the variety of data formats for simple facts makes it difficult to interchange data between sites and applications [»kentW2_1989]
