Catalog limits
Hello.
I didn't find the info in the forum : what are the actual limitations of MP database (size and number of files) ?

The limit of 1.8 Gb for the database in Expression Media is no longer present in Media Pro.
However the limit of 128.000 media items still is..
(Per catalog)

Thank you for the answer.
If I understand well : it is now possible to choice the integration of previews in the catalog without any problem (according to the size of the database).0 -
yes, this does implicate it.
However, i can not confirm it with my own experiences.
Perhaps someone else?

Direct information received from the developpement team (Owahl) :
The correct information is : there is not a limit on 128.000 images and archive is no more down to 1.9 GB

Wrong! I've just tried adding images to a test catalogue I created for when v1.0 was released. That stopped working at 127,999 images. Adding a new folder to this catalogue causes it to crash. This is on Windows XP. It didn't even have the decency to say "there is a problem" or produce an error dump.
As for the wisdom of having large catalogues... I've learnt to work around this. As my images are available on disk I don't bother with previews. If I were to include these in my catalogues then I guess that some of my files would be well over 4GB in size. The practicalities of having files this sizes then starts to become an issue. Whenever I finish working I copy my catalogues to another disk for backup purposes. Having such large catalogue files would significantly slow this down. Also you can't back them up to other media easily i.e you have to span files across DVDs or use Blu-Ray. This is assuming you consider backing up catalogues important! I move my annotation work back and forth between a desktop and laptop and would find such large files a major slowdown for this.
I've got used to having catalogues per year and will be sticking with it, even if Phase One were to admit to and fix this problem.

Thank you for the info.
128 000 is enough for me... It would take some time before I reach such number of files !
I don't include previews in catalog. As you say, backup is important both for catalog and, of course, for files themselves. I use 3 h.d. (1 internal, 2 external) and I make also backups on DVD. About backup, I must say that I am careful for the files, less for the catalogs. Perhaps because I always write metadata in files so it's easy to recreate a catalog (and fast with EM 2 or MP - regarding to other DAM).

I wish they were right but the aren't.
You can see in this movie the strange behaviour when exceeding the 128.000 boundary:I must say that I am careful for the files, less for the catalogs. Perhaps because I always write metadata in files so it's easy to recreate a catalog (and fast with EM 2 or MP - regarding to other DAM).
It's more carefull to don't 'touch' the original files and put all metadat into the catalog instead...(Btw, i do the same as you but this is advice from Peter's book đ )

I am ready to believe this but I read exactly the opposite from many people...
If metadata are written into the files there is no more possibility to loose them only by loosing the catalog... âšī¸ How is it possible to redo a catalog without metadata â
Then, write (and re-write as many times as it is necessary) metadata in files does not touch the picture itself. So, where is the problem ? What does Peter's book says about ? In an other way : why is it "more carefull" to don't touch the original files ?
(I ask the question not to convince you because I see you do like me, but I suppose you have read the book and you know the reasons)0 -
Lion, you'd rather corrupt and lose your original or your metadata ?
When you save your metadata, you can corrupt your files...0 -
yes, everytime you 'touch' your file there is some risk of corruption.
A second 'problem' is that the file itself has changed in this scenario so it's complicating your back-up (i.e. when you are following Peter Krogh's 'bucket system').
So, in his mind it's better to leave the images untouched once they have been catalogued. All the metadata handling and organizing has to be done in the cataloging software (i.e. EM2 of MP1). The 'only' thing you have to do is make good backups of you catalogs (3-2-1 rule).
You can find a lot of Peters ideas on dpBestflow:

1. A catalog also can be corrupted, or deleted (nobody's perfect...). And there you loose numerous hours of work.
2. Metadata are made to be embedded. The jpg format is done for this purpose. That's why the EXIT, IPTC and XMP fields are clearly separated in the file from the "picture zone".
3. I don't change metadata every day... But when it happens, I write the metadata in the file. It is - excepted the risk of corruption - the most secure way : then your metadata are both in the catalog and in the file.
4. EM 2 manual says clearly the same thing.
5. To "experiment" the risk of corruption, I re-write metadata in all my ~12 000 files (don't worry, I have backup of my photos...) : no problem.
6. The risk of corruption is no more important than the risk of a human mistake (deleting a catalog, for instance...), according to the actual hardware. Note that hardware changes in the good sense (hard disks are certainly more reliable than they were 10 years ago), not human being. Well, not always.
7. In numerous forums, Website or softwares manual (includind IDimager), photographers are advised to save their metadata into the files.
EDIT : thanks for the links. I am happy to see that I follow exactly the 1-2-3 rules : files saved both on h.d. and DVD, 3 copies (4 for me : 3 h.d. plus DVD). I like specially the 2"5 h.d., easy to carry.0
