In Austria we use 1/2 year or full year depreciation.
we distinguish between purchase date and and start date of operation - the 
later is relevant for depreciation - this is especially important for complex 
assets which consists of many separate assets.

the rule
start of operation during the first 6 month have 1 year  depreciation
start of operation during the last 6 month have  1/2 year depreciation
sale in the first 6 month 1/2 year
sale in the last 6 month full year

the depreciation is calculated as (remaining value) / (remaining years)
this allows to increase or decrease either the value or the remaining duration 
if required. A major technical improvement would increase the value and/or the 
duration of operation, technical obsolesce would decrease duration of 
operation.

for some assets like cars we distinguish between commercial and fiscal 
depreciation duration and purchase value . 

On top of this IAS rules (I am not familiar in detail) apply.

please think of allocation of depreciation to analytic accounts.

We also found it useful to allow encoding of insurance and inventory numbers 
as well as tracking of locations (warehouse, plant, workbench) where the 
assets have been and currently are.

for cost/analytic accounting it is useful to split the yearly or 6 month 
depreciation values between the relevant real periods.

for budgeting a depreciation forecast based on the current assets for up to 10 
years is helpful.

assets analysis is done for commercial and fiscal values grouped by financial 
accounts as well as analytic accounts / locations etc (task for olap ?)

we do asset accounting in full € - especially to save valuable space printing 
multi column landscape reports. 

differences between invoice lines and full € (Cents are cut off) are posted to 
special accounts.

invoices may be grouped to "projects" which in turn are activated as 1 asset. 
own workforce cost may be also part of the project and hence be activated.

sorry for being long ....
