The Matrix[1] entity supports cross-source correlation and analysis. Its <Frame> element enumerates a set of Source entities that are to be analysed together.
<Matrix Key=’key’> [ <Title> matrix-title </Title> ] [ MAT_PROTO_SUBJ | MAT_COMMENTARY | MAT_DATE ] ... [ TEXT_SEG ] ... </Matrix>
<Frame> SOURCE_LNK ... [ TEXT_SEG ] ... </Frame>
<ProtoPerson { DetKey=’key’ || Key=’key’ }> [ <Title> proto-title </Title> ] MAT_LINK ... [ TEXT_SEG ] ... </ProtoPerson> <!-- or ProtoAnimal, ProtoPlace, ProtoGroup, ProtoEvent -->
<Commentary DetKey=’key’> [ <Title> commentary-title </Title> ] MAT_LINK ... [ TEXT_SEG ] ... </Commentary>
<ProtoDate DetKey=’key’> [ <Title> date-title </Title> ] MAT_LINK ... [ TEXT_SEG ] ... </ProtoDate>
<Link [Type=’link-type’] { DetLnk=’key’ || Value=’value’ }> [ TEXT_SEG ] ... </Link>
The Matrix entity is typically used to compare/contrast the profiled sources from a number of Source entities. This would usually be to solve a specific problem, or to study a given person or family, and contrasts with the Source entities themselves which are designed to assimilate one source each for any future study.
