ids - Best practice
Hi all,
So a question on usage of id's I have a lot of extra info I want to add (and make searchable) to my books. This is info of a certain type having 1 or 2 values for a book (like ISBN (can also have 2 values 10 AND 13)). So my question is (also consider coming versions of calibre that may introduce specific fields for this info), should I put info like this into id's, or is there a better way: both isbn 10 AND 13 NUR (3 digit number representing a main genre group) NUGI (obsolete 3 digit number, replaced by NUR no 1-1 mapping) Original Title Cover type (soft cover hard cover) Image type (full color, BW, 4-color) Quality (Photo, OCR, direct text) Offline status (true / false - indicating having a paper copy) |

ISBN 10 and 13 are basically the Same number. 978ISBN-10(sans check digit)new check-digit) Cover: there is Trade Paper and Mass Market for Soft, Quality:Image, UC_OCR, A,B or C(grade)_OCR, Native (from Author source file) Image type: Of the cover? Illustrations? (not even considering Manga ) I have been using a tag for 'offline status' If Calibre introduces a new field that you have, you can use 'Search and Replace' to migrate your data IMHO use Text with fixed set of values for Quality, Cover to control uniformity of entries. |

Thank you.
I had the idea of using s/r when there where new fields indeed. My reason for using ids is to have some less labels (Quality.Image, Quality.OCR are 2 labels against Quality with multiple values) But also to have some quick options like ImageType:False and tags:comic to find comics not having set the type of used images. What is your reason for using Text in stead of ids? |

So you use a textfield with some pre-defined text I use e.g. coverQuality:BW-Photocopy or NUR:331 Besides the predefined info what is the main-advantage of using your implementation over mine. My main reason is that I now can click fast in the id's section to find books not having set the NUR-info I have tons of labels (sorted with sub-labeling (.)) using this id-info is a faster way to work with it. I'm thinking of types to add there. The NUR and NUGI (dutch library-sort-codes) are identifiers in a way that they are a representation of the used genre. So main-question: Should I add this in IDs or in your explained text-fields and what are the (dis-)advantages of the purposed method. |

Putting that info in the ids field sounds very wrong to me. They are not an "identifier" which uniquely identifies a book, they are a code that defines some aspect of a book. And they are going to be a pain for you to maintain all squashed into that identifier textbox.
A custom column is the recommended approach. As for quick access, I assume you mean via the tag browser? You can have custom columns displayed in the tag browser too if you tick the "Show in tags browser" checkbox in the custom column edit dialog. |
