POWLA provides an OWL2/DL implementation of a generic data model for linguistic annotation (Chiarcos 2012ab).
The immediate predecessor of POWLA is the PAULA data model (Chiarcos et al., 2008), and the associated XML standoff format (Götze et al., 2005; Dipper 2005). PAULA (and POWLA) implements the data model of the Linguistic Annotation Framework as described by Ide and Romary (2004). POWLA is thus semantically equivalent with the LAF data model and the GrAF format (Ide and Suderman, 2007), i.e., ISO 24612:2012.
History:
2018-04-03 deprecate powla:rootOfDocument in favor of powla:hasLayer (partial inverse)
2018-04-01 deprecate powla:endPosition, powla.startPosition in favor of powla:end, powla:start; deprecate powla:hasMetadata in favor of a generalization of powla:hasAnnotation
2018-03-27 deprecate powla:nextNode and powla:previousNode in favor of powla:next, powla:previous
2012-02-23 initial release of the OWL/DL implementation
2008-05-15 abstract data model published (PAULA 1.1, Chiarcos et al. 2008)
