Measuring Information/ specified complexity
If it is something straight-forward such as a definition, we can count the number of bits in that definition to find out how much information it contains.
aardvark: a large burrowing nocturnal mammal (Orycteropus afer) of sub-Saharan Africa that has a long snout, extensible tongue, powerful claws, large ears, and heavy tail and feeds especially on termites and ants
A simple character count reveals 202 characters which translates into 1010 bits of information/ specified complexity..
Now what do we do when all we have is an object?
One way of figuring out how much information it contains is to figure out how (the simplest way) to make it.
Then you write down the procedure without wasting words/ characters and count those bits.
That will give you an idea of the minimal information it contains.
I say that because all the information that goes into making something is therefor contained by it.
And if you already have the instructions and want to measure the information?
Again just count the bits in the instructions.
For example a cake would, at a minimum, contain all the information in the recipe.
Have you ever had to assemble something?
The object you assembled would, at a minimum, contain all the information in the assembly instructions.
