Open PAF now!
Errrr? Isn't that what VAT and corporation tax is for? Those will return the value of Open Data to the taxpayer without the need for costly and unnecessary bureaucracy and that is why the 'fair value' licence shouldn't apply to public data. Before you say what about the Googles and Vodaphones who don't pay tax, that's a completely separate problem that needs to be solved anyway. They wouldn't be bothered by the few crumbs of tax on re-using Public Data. At the moment Google are voting with their cheque book and refusing to licence PAF data for use on their maps, where it would be valuable for their users, but wouldn't increase traffic enough to justify paying.
If your attitude had held sway as the internet and www developed they would be crippled by tollgates and micropayments making up much of the traffic. It is the open environment that reaps dividends and creates value and that environment is now an essential infrastructure even while vested interests try to undermine the principle. Public core reference data such as postcodes and addresses is a similar infrastructure whose use needs to be maximised not tied up in complex licences and expensive fee collecting mechanisms.
Anyone fancy paying for DNS lookups on the internet? Making people pay for postcode or address look ups on the internet or in the 'real' is similarly daft!
That's why we need to open the Postcode Address File now and not cripple its use by excessive upstream charging or cumbersome licensing.
