collection mgt

• typical collections : books , films , music , strips , but also : wine , tools , inventory, cards etc
• collections items need not to be digital per se (such as a wine collection or an inventory )
• collection mgt apps manage these collections digitally , instead of cards , paper list or digital lists in excel etc

architecture

collection mgt is about managing meta data :
digitally, these can be stored managed with these methods

1. use file extended attributes , see : extended file attributes
   for some colections there are protocls : f.i. music ID3 , image : exif metadata
   file extended attributes can be problematic , because depending on file system

2. use a proper ‘database’ to store meta data
   this approch is most often used
   ‘database’ : it could also be xml or json files

3. include metadata in the file content
   html , properties in ms office files, yaml headers in text files , etc

4. (wm ) create a second file with identical name and a speciic extention ( .wmmeta)

considerations

• ! is the content left as a file or imported as a blob into a database ?
• if content is file based , can the app track file delteds, moves , renames ?
• how does the app handle metadata

specialized apps

• a pswd mgr could be considerd a special type of a collection mgr
• books : calibre & co
