Kathi Reed posted an interesting item on her Ancestor Search Blog on 12 September 2012 that I haven't seen referred to or posted anywhere else. It appeared on the Ancestry.com Customer Help page (see What are the differences between the Family Tree Maker and Ancestry.com trees when using TreeSync™?).
Here is what it says:
Most content in trees is uploaded and/or synced seamlessly between Family Tree Maker and Ancestry. However, because Ancestry.com and Family Tree Maker trees are in different formats, there are a few differences you should be aware of.
In general fact dates, names, places, and descriptions (including custom and alternate facts) are the same in Family Tree Maker and Ancestry trees. However, you may find that some fact types are labeled differently. For example, the Physical Description fact in Family Tree Maker is the Description fact in Ancestry trees.
- The caption of a media item in Family Tree Maker is the same as the Picture name field on Ancestry.
- Audio and video items are not transferred between Family Tree Maker and Ancestry.
- Media items attached to relationships in Family Tree Maker are not uploaded to Ancestry.com.
- Records you’ve found on Ancestry.com and merged into Family Tree Maker won’t be re-uploaded to Ancestry.
- Documents in Family Tree Maker will be uploaded to an Ancestry tree only if they are in one of these formats: .pdf, .doc, .txt, .rtf, and .htm.
- Photos uploaded to Ancestry Member Trees cannot exceed 15MB, so a photo in your desktop tree that exceed this size limit will be resized when it is copied to Ancestry—your original file will not be affected. Images need to be in one of these formats: .jpeg, .bmp, .png, .gif, and .tiff.
In Family Tree Maker you can create a variety of notes: person, research, fact, relationship, media, and source citation. When you upload a tree to Ancestry only person notes will be included; they can only be viewed by people you have invited to your online tree.
If you have entered shortened display names for locations or custom GPS coordinates in Family Tree Maker, they will not be included in your Ancestry tree.
Saved reports, charts, and books cannot be transferred from Family Tree Maker to Ancestry.
In Family Tree Maker only you can view information you’ve entered for a living individual. In your Ancestry tree, anyone who is invited to your tree can view information about living individuals.
- Sources created in Family Tree Maker using source templates will transfer to Ancestry, but you cannot edit these sources online.
- Media items attached to source citations in Family Tree Maker will be uploaded; media items attached to sources in Family Tree Maker will not be uploaded.
- A story created on Ancestry.com will become a .htm file in Family Tree Maker, which can be viewed in a Web browser. You can edit the text in a word-processing program.
- Smart Stories created in Family Tree Maker will become .rtf text files in Ancestry. The story can’t be viewed within your Ancestry tree but the document can be down¬loaded. (Smart Stories are uploaded only if they are attached to individuals.)
* "Records you’ve found on Ancestry.com and merged into Family Tree Maker won’t be re-uploaded to Ancestry." I'm confused here - does this mean if I've found a record on Ancestry.com and attached as a media item using FTM WebSearch won't be re-uploaded? Or does it mean that a record I found on Ancestry.com, downloaded to my hard drive, and attached as a media item in FTM won't be re-uploaded? I'm guessing that the second image would be uploaded to Ancestry, since I probably renamed the file in my computer files before attaching it to a person in my FTM file.
* "In Family Tree Maker you can create a variety of notes: person, research, fact, relationship, media, and source citation. When you upload a tree to Ancestry only person notes will be included; " If I have non-person notes in my FTM file, and sync it to Ancestry, will the non-person notes still be in my FTM file? I think they will. However, if something goes wrong with a sync, and I have to use the Ancestry tree to start again, will those non-person notes be included?
* "Media items attached to source citations in Family Tree Maker will be uploaded; media items attached to sources in Family Tree Maker will not be uploaded." Do people attach media to sources, and not to source citations? I can think of some reasons to do that - attach an image of the front page or copyright page of a book or periodical issue.
* "Smart Stories created in Family Tree Maker will become .rtf text files in Ancestry. The story can’t be viewed within your Ancestry tree but the document can be down¬loaded. (Smart Stories are uploaded only if they are attached to individuals.)" This surprised me - I've always thought that the purpose of "Smart Stories" was to be able to sync with a "Story" on an Ancestry Member Tree. I was wrong, apparently (not the first time!).
I also found it interesting that this appeared in the Ancestry.com Customer Help section but is not (yet) on the Family Tree Maker Knowledge Base. I think that it will be, however.
There are several other items in the Ancestry Customer Help database concerning Family Tree Maker 2012:
* What’s new in Family Tree Maker 2012
* Using the new TreeSync
* TreeSync Frequently Asked Questions
In summary, I think that being able to synchronize "almost all" data between an Ancestry Member Tree and a Family Tree Maker 2012 database is a significant advance in technology. This is a real advance for Ancestry and FTM that will advance FTM 2012 sales and AMT use. However, there will be a major social problem for Ancestry/FTM IF there are significant sync problems that cause users to lose data. In other words, they need to get it right the first time out of the box.
