[open-government] Retrieval of company revenues

[Antoine Logean]

Dear all,

In a project we have to solve the following problem:

We have a long list of company names and we would like to retrieve for each
company the annual revenue. As it is a pretty straight forward information
that can be useful in many different context, I imagine that there are
already such existing resources/services.

For companies that are on the stocks market I could use yahoo Finance,
Google finance or MSM money.

The problem start by private companies. As they are not on the stock
market, they do not have the obligation to share financial data as public
companies and the information they share is not consistent or regulated.
Here I have found some existing services like

- http://www.manta.com
- http://www.hoovers.com
- http://www.mergentonline.com

As I do not want to re-invent the wheel, I would have the following
questions:

- is it a kind of standard format (unique identifier) to identify a company
? If I had to implement that, what would be the best way to do this ?
- is there an existing open company index/register that aggregate various
economical information about companies ?
- is there already RDF vocabularies existing to describe such economical
information about companies ?

I would be interested in any information, links & hints that could help me
to solve this problem.

Thanks in advance for your help.

Kind regards

Antoine Logean
