We'd like to have an inventory system for cataloguing the space's equipment and supplies.
We'd like to have an inventory system for cataloguing the space's equipment and supplies.
For now we're going to see how the [[Inventory]] page evolves, and then look in to what enhancements we need to make - if any.
== Ideas ==
Here are some ideas I've had for the project, would appreciate comments. --[[User:Robert|Robert]] 13:33, 8 August 2010 (UTC)
The primary goal is to produce a flexible system for people who have an interest in keeping the inventory system up to date and comprehensive, while at the same time making it so people who don't care can accomplish what they need to in as little time as possible.

; List: The application is centred around one list that contains all equipment, components, etc.
; Item: The list is composed of items.
; Categories: All items have one category.
:;: For example:
::: Component
; Properties: Each item has properties common to all item types, and ones unique to its category.
:; For example (common):
:: Wiki page
:: Date acquired
:: Quantity
:: Identification description
:: Category
:: Location
:: Owner (defaults to "Hackspace Foundation")
:; For example (unique to "Components"):
:: Reorder URL
:: Reorder Price
; Queue: Items can be placed in to one or more queues, and can appear in queues multiple times (providing there is only one unresolved occurrence), to be processed at a later point.
:; For example:
:: Reorder
:: Stock check
:: Disposal
; Queue items: Linked to a regular item (extension of), but with the additional properties "Resolution" and "Resolution date" and attached to a queue.
; Relation: Similar objects can be linked together, this can be resolved recursively up to a limit.
; Log: All changes appear in a log with a change description, previous value, new value, user, and time.

Status: Another hackspace has created a project called PartKeepr which looks ideal for this purpose.

We'd like to have an inventory system for cataloguing the space's equipment and supplies.
