Collecting guide

How to Catalogue Any Collection

Any object that fits none of the other categories; describe it with the general data sheet.

Not every collection fits a category. Keys, bottle caps, snow globes, typewriters, thimbles: whatever you collect, the same core record makes it identifiable, insurable and interesting to others. ordicio uses the Object ID standard for this - the checklist museums, police and insurers use to describe objects so that they can be recognised if they are ever lost or stolen.

What to Record

Object ID asks for:

Add the collector’s own records:

Getting Started

Give each object a number and keep it with the object. Write the record when the object enters your collection, while you still remember where it came from. If a category in ordicio fits later, you can change the category and keep everything you recorded.

Care and Storage

Keep objects away from direct sunlight, heat and damp, which harm almost every material. Store documents and receipts with the record of the object they belong to.
