And, I'm told, you can put the image link into the Source template which does have a repository field. I'm not enchanted with that field, unless the repository is Library of Congress or the Family History Library; no other US library is nearly as disaster-proof -- and even LoC burned once. Having that available though doesn't cure my problem of not instantly recognizing which of 12 men of the same name and birthdate is the one I want and which 11 are data-holders only. > So, for example, I can download a household image as a PDF for the Irish > 1911 census (*free* - shame on the GB census!), enter it into the > Gallery and link to the family record, to each member of the household > and to the Place record.

Yes, PAF too is said to handle audio and video, but since a majority of my ancestors died before that technology was invented it's even less useful. (g) Cheryl
I concur with Cheryl. Basically all genealogical applications allow their records to contain links to external items, either files on the local file system or to URL on the world wide web. That doesn't solve the problem of where to store those links. As Cheryl points out, if you put a link in a person record, you are making the explicit statement that the linked-to evidence refers to that person. The question I am trying to get to in this thread, is how are you going to handle that evidence, a link to an external something or other in this case, when you don't yet know what person should link to it?

Bob, I've used nFS and read all the API documentation. They have personas and persons and the user interface allows you to rearrange personas within persons. It's a two-tier system. I think it's a great example of how personas can be made to work. I think their data is pretty stinky, but that has no bearing on the technique in my opinion. >> Eventually every genealogist reaches the point when he or she has delved >> far enougback in time that the solid, firm trail of records has dried up. > I don't ever expect to reach that point.

What I think you are saying is that you never plan to have to cross the chasm from person-based genealogy to record-based genealogy. The whole genealogical application business, in my opinion, caters to people who believe that. Obviously from all I've written about this, I don't believe that. At my point in genealogical research I have 1000s of records that I haven't been able to assign to real people yet. Here is my overall genealogical project. I descend from Loyalist Wetmores who were exiled to Canada at the end of the American Revolutionary War. By the 1850s many of the children and grandchildren of those families were returning to the United States where the economy was stronger. I descend from one of those returning families. My project is to understand that return migration by finding all the families who were involved, what their patterns of migration were, where they ended up, and where all their descendants are living now. This is a full research project. It is definitely a record-based project. You can probably understand my needs for effective ways to record all my evidence so I can access it in many ways to support the process of making conclusions. You might argue that this project is not a genealogical project, but rather a historical project, so I have no business expecting a genealogical application to be able to support me. I don't see it that way. I believe that genealogy is history, and the farther back in time we go, the more we have to act like historians to make progress. I want a genealogical application that can support what I am doing with this project. Tom

For my French work, I use a separate spreadsheet page for each type of record for each parish, so that the most common data items found in extracted records is all in the same column(s), and more or less in the same format. I still can put have some freeform notes off to the right, but I don't commonly need to. I also generate pages that have the same records sorted on various keys. I then in a separate pass, may add the people in these records to a data base and link them together based on parentage or espousal, when I can identify the people. In my case, probably 90% of all people in one kinds of record, show up in some other record (either as parent or spouse, or a death record for someone who was born), and I thus end up with a huge and convoluted tree relating almost everyone to everyone else. But this is totally separate from my spreadsheets of source data. lojbab --- Bob LeChevalier - artificial linguist; genealogist [email protected] Lojban language www.lojban.org

Gramps has a feature which I do sometimes use for handling evidence files but AFAIK it just points to a file it's told about. I don't think it makes a copy in the database. > My answer is that genealogical programs should be able to handle evidence, > but no one has figured out how to do it yet. Figured but not done. If you look back to the thread "Data import from the new Familysearch site" I have an XML example where the "evidence" is copy & pasted from the web-page: <SourceObjects> <SourceObject> <Content><![CDATA[Name: Mary Collier Gender: Female Baptism/Christening Date: 27 Dec 1760 Baptism/Christening Place: ALMONDBURY,YORK,ENGLAND Birth Date: Birthplace: Death Date: Name Note: Race: Father's Name: George Collier Father's Birthplace: Father's Age: Mother's Name: Mother's Birthplace: Mother's Age: Indexing Project (Batch) Number: P01712-1 System Origin: England-ODM Source Film Number: 230649 Reference Number:]]> </Content> <ObjectID>1C42DFF7-299E-44C8-91FB-F5A805A78AAE</ObjectID> <MimeType>text/plain</MimeType> </SourceObject> </SourceObjects> Several points: 1. The object itself is wrapped up with a mime type ( http://en.wikipedia.org/wiki/MIME ). This tells the program how to display it, assuming the program can handle that type itself, or pass it on to whatever utility the OS has associated with that type. 2. As a consequence of the above the system is future-proofed. If some new format is introduced then provided that a mime type is provided then it can be handled. 3. A collection of objects can be wrapped in a binder. This makes provision for multi-page scans, scan and transcription, transcript and translation or whatever. 4. This is intended to be a publication medium. 5. A UUID is provided. This means that if I send a copy of this object to you and someone else who has also received a copy sends a further copy to you your S/W will be able to identify and discard the duplicate. 6. A consequence of 4 & 5 is that once the object is published it should not be amended. If someone wants to make some amendment, such as provide a transcript to a scan, a translation to a transcript, etc. it should be done as a separate object with a pointer to the original. 7. There are a few changes I'd make. Firstly the binder object should have the UUID instead of the inner to discourage braking up the object. Secondly there should be text as a human-readable title/description/handle to the inner object. Thirdly there needs to be a content encoding element as well as the mime type although this could be optional. 8. The whole shebang, binder and all, would best be enclosed in a further wrapper with its own UUID, a UUID pointing further up the source tree and other information such as text to be used as a citation. In the case of an amendment record the source UUID would be that of the amended record. Note that this is an external representation. S/W realisations would be free to store the data in an RDBMS or whatever. -- Ian The Hotmail address is my spam-bin. Real mail address is iang at austonley org uk

You look at the physical records, you decide who the persons were who are mentioned in those records, you go you your genealogy program and you find the appropriate person records, creating them if need be, and you edit in the new information. In other words you extract information from the physical records and you add that information directly to person records.

After you create the source records for where the physical records came from, you edit those source records, adding to them the information that you got from those sources that you believe is important. You probably have to do this as "unstructured notes." Then you link persons to those sources and you also "copy up" from the stuff you added to the source records into the person records. > Here's another possibility advocated by programs like Gramps for Family Tree Maker. You first create event records from information in the physical records, say a birth or death or marriage events, and then you add a link from some person in your database, creating that person record if need be, to that event record. The events really don't stand alone; you have to link person records to them. As I understand it, what NFS did with IGI records which were transcriptions, is that it turned each such transcription into an association of personas, represented in the source record. Thus a transcribed marriage has two spouses, probably a marriage date and location, and possibly parents. The personas involved in a given transcription are not linked to any other data. Later, users can then selected various "personas" representing raw data and "combine" them into a compound or derived persona representing more completely what they think is the data applicable to a single person. Someone else could combine different extracted source personas into a different compound. The original source persona still exists, as does any combined ones. In theory, one can determine whether a persona is extracted data or derived, but in practice the LDS source data is incredibly verbose and redundant, and so uninformative unless you know what to look for (somewhere deep in the record, one can find the same sorts of things one could find in the old IGI records to distinguish an extracted from a submitted record).

I don't think one ought to mix results with process. In fact, one ought to have two processes -- one double-checks the other for legitimacy; keeping research/evidence on paper and transferring it to the database provides both the separation of tasks AND the cross-check.

Have a separate entity for your "higher level person" and then link entities between that and the personae records. At a minimum the link could simply contain pointers in each direction but you could expand it to contain a note and maybe some value to indicate your confidence - including negative values to say you think the persona does not refer to that person.

And that's back to the Research Data Filer (RDF) that came with early versions of PAF. You keep the paper evidence, and the computer indexes them -- something computers are particularly good at.

However... You are perhaps wanting things to be all one way rather than another and are in danger of missing the point which is that evidence can be stored at a number of levels, physical and virtual, according to its perceived usefulness. I retain (almost) all evidence on paper, but selected evidence is then also stored on computer. It is simply too much effort to store all possible evidence in a useful form on computer, so some pre-sifting makes life easier, in fact it makes the job practicable. Now the interesting question is since you have the paper based evidence, how much of a particular item do you store on a computer? In practice, this computer data might be just a reference, or it might be all the relevant data. It could even be all the information in that piece of evidence and including what sort of paper, what colour, what condition and so on, but that would be unusual and remarkably keen. The amount will depend on what you want to do with it on the computer. Do you see the picture? Peter

For all my interest in computers, my real underlying interest is in information. Computers are only a tool to help dealing with this. I keep the evidence (and some printouts) in lever arch files roughly organised on a surname basis. Yes, you can take several pieces of paper and spread them out in front of you to study and compare them. That is something you cannot do on a computer. The issue of evidence for people you MIGHT be interested in is a good point. However, my feeling is that throwing it all straight onto a computer is likely to be unhelpful even if the software can cope. Peter

I have described my current thoughts for "doing genealogical research" as building up "person-trees" with personae (person records codified directly from evidence records) at the leaves and higher level person records as the roots and "interior nodes" of the trees. This is a bit of a simplification since it ignores issues of events codified from evidence, levels of confidence, adding notes, adding conclusions, and so forth. My entire model is a bit more complex that the simple tree of persons idea, but these concepts seem subtle enough that I hesitate to obfuscate the core ideas with that complexity. I guess I'm trying to say that my overall model does include the points you have just mentioned. Thanks. Tom

I keep evidence in various ways depending on the type. What I am interested in is what is the best way to represent your evidence when you have lots of evidence about as-yet unknown persons, and you are going through the inference process of deciding who those persons are. I would have difficulty handling 100 index cards, or 100 pieces of paper, or having 100 image files open on my computer. I would want a way of putting, say, these five together in a group as a tentative person, and those 15 as another tentative person, and so on. It's hard for me to do this grouping and thinking with paper, cards, open windows. I need some other mechanism to help me. So I'll keep my evidence on paper or in image files, as we all do, but I'm looking for some additional "codified" form of the evidence as more or less similarly-formated records on my computer so I can easily compare and group them. We are getting some good answers about this on this thread now. Tom
