Well said David. I'm not sure how much involvement the software vendors had in those early standards like Fortran. However, with languages like C++ I think most of the big vendors are represented on the standards body. These same companies have "language lawyers" though that interpret those standards, and often hide behind 'the letter' rather than embracing 'the word' The older ANSI C and ANSI SQL specs are abomininations resulting from a design-by-committee approach. You can understand the approach taken with Java whereby it was designed and evolved as a proprietary standard before being considered for an international standard. I think the industry has benefited in the long term, albeit via an evolutionary approach. Programming Languages are better defined now, and more functional, and with less variation between vendor or hardware. I think genealogy could learn a lot from the programming language history. Its biggest problem, though, seems to be its fragmentation - there aren't the same big companies or authoritative bodies around to help kick-start a new standard.

I agree about the data model coming first Ian. However, it seems there's no absolute consensus on what such the data model should encompass. Every time the GEDCOM issue comes up, it seems some very experienced people make excellent critiques of the GEDCOM model, and enumerate all sorts of events, relationships, data-types, etc., that should be included in any new model or format. If this were a new computer language that was to be defined then some authoritative body (possibly a recognised standards body) would put out an RFI (Request for Information) to the public before creating a specification or data model. Although there are several genealogical bodies around, I'm not aware of any that have taken this initiative, or feel any need to. If they did then would the people/companies with software interests respect their authority anyway? I would argue (and have done elsewhere in this thread) that defining a better data model would eventually catch up with the popular software products - and make them better products. There is no such product that currently does everything. Most are great for home use, but less so for the serious genealogical researcher. Once such a data model had been ratified then the door would be open to producing an upgraded GEDCOM (or possibly an entirely new, more modern interchange format), and an open spec for an OOP object model designed around the data model, and eventually new enhanced versions of the popular products. In effect, I guess I'm saying that software designers can't be expect to know all the ins-and-outs of serious genealogical research, and vice versa.

Any intellectual property issue that arose from writing a file in a proprietary format would also arise from reading it, I would think. And generally the issue is patents, not copyrights. I can't think of any copyrightable aspect of a file format, other than the vendor's documents concerning it. I can think of other reasons not to write, including (1) being bound by the terms of a non-disclosure agreement, or the fact that (2) writing is much harder to do correctly than reading. I've also declined to make source code available for file formats I've reverse-engineered. - Ernie http://home.comcast.net/~erniew

That's the point. You say exactly the same thing I do: there is only ONE data model, beyond that, there is lots of data, but it can;t be forced into a "model". Doug McDonald

The solution now in place is to provide a 'universal' gedcom reader (it works fairly well although is not 100% effective) and for gedcom output to provide 5.5 conformity. That is backed up by the more comprehensive Gendatam data structure. It does mean that on a strictly gedcom operation you may lose some of the data on output that was in the input file (or maybe it goes into notes where it is not so easily accessible), but that is not always a problem - it depends on what you are trying to do. The problem is with vendor extensions, but one should expect the 'core' data to be always handled correctly. One development test with Gendatam Suite has been the 'multiple round-trip'. This works as follows: import your gedcom file them write it out as a new gedcom file. This output file will differ textually from the original for all sorts of reasons, not just data loss. Re-import this file and output again as a new file. Does this second new file differ from the first new file? Repeat the cycle a few more times and see if any differences arise. The point of all that is to see how stable the data handling is beyond the initial cycle. If you want to keep all the data you have successfully imported, you need to save it as a gendatam file, not gedcom. A feature of Gendatam Suite, intended to ease difficulties, is the principle of providing data access. This means that the native gendatam file format is published. Also that data is accessible on screen and may be output in a variety of ways including as a plain-text report file. The intention is to allow people who have a reasonable degree of computer literacy to access data in a way convenient and useful to them. In summary, I don't think there is a solution to the Gedcom standards issue unless the user has a reasonable degree of computer literacy and is prepared to use it. In practice this often seems to involve using multiple programs as a toolkit to provide the required functionality, but that is just real-world computing. Regards Peter

Every person had exactly one mother and one father. Period. (Today a baby can have two mothers, five years from now, a total of 47 parents, 46 chromosomes and the mitochondria, but we won't worry about that.) That's a very simple data model. You have people, and you have that relationship. That's what genealogy is. Then you can accrete tons of data on top of it. Once you accrete, there is one clear fact: there simply is no "data model". There is no way to pre-guess every possible data connection between the main items, which remain the individual and their parents. You can accrete "relations" between genealogically unrelated people. No one can ever make a "standard" to encompass all this. Doug McDonald

Ancestry is too greedy for peoples money and Mormons don't want to give up their money so that everyone can access the information at the Family History Centers. From what I was told from a Mormon friend of my that volunteers at a Family History Center they Mormon Church dropped Ancestry because Ancestry wants too much money for their subscriptions per computer not per Family History Center. Mormons are too cheap to pay the expensive prices that Ancestry wants and Ancestry is too greedy to lower their prices.

For example if you download a Gedcom from Rootsweb.com or familysearch.org and want to add it to your file. Merging with Legacy Family Tree is so much easier and quicker than PAF. One of these days the Mormons are going to create a version of PAF that has a great merge like Legacy Family Tree. But odds are they are not going too.

Something, because all were involved in its creation, all could/would agree to? Surely, a core standard, perhaps based on gedcom 5.5, with some scope for, ahh, individuality could be arrived at? Right now, it seems to me, the problem isn't with gedcom but with the way it's interpreted by the various software houses - if it's a standard, there's little or no enforcement, no "GoodHousekeeping Seal of Approval" or UL listing. It's not for me as a user to enforce the standard, save by refusing to purchase software that, in my opinion, is non-compliant. Bob Melson -- Robert G.

The program I use for first entry creates primary relationships of Individual-Father and Individual-Mother. You enter the details of the individual, and then the RIN of the father in the fagther field, and the RIN of the mother in the Mother field. If the father and mother were married, you endter the rin of the spouse in the spouse field, but that is something separate from the parent-child relationship. When I export the data to GEDCOM, the export program tells me that it "created" "family" records, because GEDCOM required it. The program itself can list all the children of one parent, rather than having to print two or more family group sheets.
