Hi Mark, I'll just comment in quickly. The model is not aesthetically pleasing, but it works.
Once you drop Leos assumption that a new nco:Contact has to be made for every single instance of to, from, cc, bcc or every email, and, instead, modify it to only create those in case the email address does not exist, the model will not be really replicating that much datat. It will not make intuitive sense at any point, especially with the PersonContact being a subclass of Contact, which is really confusing me a lot, but the model does work, so it's hard to say it's a bug in the ontology structure, it's much more of a problem in naming convention, and perhaps the inheritance of that class, so, I do agree with you totally Mark, but I do see Leos point. Here is an example: I first define 2 person contacts, me and darron and email addresses for both. then I define the contacts related to the email, and then the email object. Now, the link between PersonContacts and the Contact objects will of course happen through the EmailAddress object (or the uris). Notice that Darron has a different name in his Contact instance than in his personcontact instance. I also added cc contact that doesn't even have a name, nor a personcontact. The email has now headers that cover sender, to and cc, but these are redundant with the contact mapping, so they could indeed be dropped. <mailto:[email protected]> a nco:EmailAddress; nco:emailAddress "[email protected]". <urn:uuid:1> a nco:PersonContact; nco:fullname "Me Myself"; nco:nameGiven "Me"; nco:nameFamily "Myself"; nco:birthDate "2008-01-01"; nco:hasEmailAddress <mailto:[email protected]>. <mailto:[email protected]> a nco:EmailAddress; nco:emailAddress "[email protected]". <mailto:[email protected]> a nco:EmailAddress; nco:emailAddress "[email protected]". <urn:uuid:1629001709> a nco:PersonContact; nco:fullname "Darron Davison"; nco:nameGiven "Darron"; nco:nameFamily "Davison"; nco:birthDate "1930-01-04"; nco:title "Sales Representative Computers"; nco:hasEmailAddress <mailto:[email protected]>; nco:hasEmailAddress <mailto:[email protected]>; nco:hasPhoneNumber <tel:+14849562430>; nco:hasPostalAddress <urn:uuid:2118792036>. <urn:uuid:[email protected]> a nco:Contact; nco:fullname "Darron Davison duisaliquam WORK ACCOUNT "; nco:emailAddress "[email protected]". <urn:uuid:[email protected]> a nco:Contact; nco:fullname "Me Myself"; nco:hasEmailAddress <mailto:[email protected]>. <urn:uuid:[email protected]> a nco:Contact; nco:hasEmailAddress <mailto:[email protected]>. <urn:uuid:597366485> a nmo:Email; nmo:to <urn:uuid:[email protected]>; nmo:from <urn:uuid:[email protected]>; nmo:cc <urn:uuid:[email protected]>; nmo:sentDate "2008-10-20T15:28:21"; nmo:receivedDate "2008-10-20T15:28:59"; nmo:contentMimeType "text/plain"; nmo:messageHeader [nmo:headerName "User-Agent"; nmo:headerValue "tin/unoff-1.3-BETA-970813 (UNIX) (Linux/2.0.30 (i486)) "]; nmo:messageHeader [nmo:headerName "from"; nmo:headerValue "[email protected]"]; nmo:messageHeader [nmo:headerName "to"; nmo:headerValue "[email protected]"]; nmo:messageHeader [nmo:headerName "cc"; nmo:headerValue "[email protected]"]; nmo:messageSubject "Commodoconsequat tationullamcorper in feugait hendrerit te duis te aliquam lobortis.
