2 Overview Archive documents vs genealogy Need for abstraction A2A Entities Into the XML syntax How about semantics? The future of A2A Questions/discussion

3 Archive documents vs genealogy

4 Need for abstraction WieWasWie was to be a central search platform for 25+ organizations Not only 11 different sourcetypes, but also different versions of the same sourcetype Uniform template enforcement But also extensibility

5 A2A Entities (1/2)

6 A2A Entities (2/2) IsXML? IsA2A? IsSourceType?

13 How about semantics? (2/2) Form definitions xml based building blocks <Form xmlns:xsd=" xmlns:xsi=" SourceType="BS Overlijden" MinPersons="1" MinEvents="1" MinObjects="0" RequiredFields="Place,InstitutionName" HiddenFields="" ShowEAC="false" ShowEAD="false" Remarks="Opmerking,AkteSoort"> <Persons> <Person ShowOptionalFields="WhenFilled" ShowDetails="WhenFilled" Reference="Overledene" Remarks="" Min="0" Max="1" RequiredFields="Gender" HiddenFields="FamilyName" RequiredOptionalFields="FirstName,Patronym,PrefixLastName,LastName" HasProfessions="true" ShowPersonNameDetails="WhenFilled" ShowPersonAgeDetails="WhenFilled"> <Required>false</Required> <Residence ShowDetails="WhenFilled" /> <Origin ShowDetails="WhenFilled" /> <BirthPlace ShowDetails="WhenFilled" /> <BirthDate ShowDetails="WhenFilled" /> </Person> <Person ShowOptionalFields="WhenFilled" ShowDetails="WhenFilled" Reference="Vader" Remarks="" Min="0" Max="1" RequiredFields="" HiddenFields="FamilyName" RequiredOptionalFields="" HasProfessions="true" ShowPersonNameDetails="WhenFilled" ShowPersonAgeDetails="WhenFilled"> <Required>false</Required> <Residence ShowDetails="WhenFilled" /> <Origin ShowDetails="WhenFilled" /> <BirthPlace ShowDetails="WhenFilled" /> <BirthDate ShowDetails="WhenFilled" /> </Person> </Persons> (...)

14 The future of A2A Maintenance A2A by CBG More SourceTypes, more EventTypes, more RelationPP and RelationEP types Changing max-lengths of some elements Removing or restructuring some oddities Better standard for Semantics (enforcing specific SourceType structure) Storing family trees?
