	Part III – Catalogue-Based Non-Destructive Imaging What model does cataloguing software use ? Library model                                                                                                                                            Where are the images stored in a catalogue based system ? Single folder; multiple folders; or across multiple hard drives                                                                      Where does the catalogue get its initial information about the files ? From the metadata                                                                                                                                   Where does the cataloguing software store this information ? Stores the information in a central location                                                                                       What is the main organising principle of Browser based systems ? File browser cache info in the DB for quick access but the information is in the original file. The model is known as the truth is in the file.                                                                                 How do cataloguing systems organise their images ? The most up to date info is maintained in the catalogue database.  When photos are first indexed – a record is created for each photo  file containing the info about it; a preview of the image is created  and stored and can be accessed even if the file is not available;  and any metadata in the file is harvested and associated with the  photo in the catalogue and the metadata is parsed into groups  (creator name, keywords, ratings, or locations).           How does a cataloguing system make changes to an image ? Adding information like keyword just makes a note in the catalogue  record for the photo. When you make a rendering change to an  image with catalogue-based PIE software, you are changing the   information in the catalogue and in the preview that gets cached,  but not necessarily touching the original.                                                                                                        Can other programs see these changes ?                             No because it is stored in the catalogue and not with the original file. How does a cataloguing system make changes to an image available to other programs ?  It can be done if derivative files are made (JPG, TIFF, PSD OR DNG) can show the adjusted images in  way accessible to nearly any program. List 5 advantages of Cataloguing based PIE software ? Associates information with one original. Info created, stored & cross referenced in one place. Multiple rendering can be attached to a single source image and managed in the same environment. Saves space, time and confusion.             Creates useful groups of scattered images. Cataloguing programs organise by metadata, proximity in the directory structure is largely irrelevant.                      Works with offline images. Can access photos not connected to the computer.                                                                                                                                                 Eases backup and restoration tasks. It can be backed up early in the process because the original is never changed.                                                                      Generates multiple output types from a single source.                                           Give two examples of software that combine Image Cataloguing and Editing functions ?
