Use of currency amounts in tables.

Representing currency amounts in a table format is very common. For instance, see Google Financials.

In this table representation, it does not make sense to provide the currency information for each cell. Instead, it should be provided once at the table, thead, tr, or th, level, and then a td may override the default value. This is very similar to the common practice of indicating the currency and formatting in plain english: "Numbers in thousands of dollars" in the table title/subtitle or legend.

The microformat for currency amounts should provide a way to represent a default currency for all children of a table, thead, tr, or th nodes. The currency symbol/abbreviation should be optional in for elements defined as containing currency values/amounts, if a default currency has been defined in one of the ancestor elements.

Historic prices

  • West Midland Bird Club:
  • Wikipedia: Bleak House
    • "Like most Dickens novels, Bleak House was published in 19 monthly instalments, each containing 32 pages of text and two illustrations by Phiz. Each cost one shilling, except for the last, which was a double issue and cost two." Dates in the subsequent table range monthly from March 1852 - September 1853
  • Wikpedia: 1922 in Germany
    • "Despite the ending of cash payments for the rest of 1922, the main cause of Germany's inability to pay, the steady depreciation of the mark, was ongoing. Towards the end of the year it assumed a disastrous rapidity. On August 1, the US Dollar still stood at 643 Marks to the Dollar and the British Pound at 2,850 Marks to the Pound. But on September 5 the dollar had already risen to 1,440 Marks and the pound to 6,525 Marks, and in December the pound was worth between 30,000 and 40,000 marks and the dollar between 7,000 and 9,000."
  • BBC News story dated 2 January, 2001
    • "A barrel of Brent crude for February delivery came within range of $25 a barrel on Tuesday before slipping to $24.35, a closing price 48 cents above Friday's closing price of $23.87. In New York, the price of Nymex (New York Merchantile Exchange) crude reached $27.40 a barrel before settling at $27.40, a gain of 41 cents or 1.5% on the day. Nymex oil prices in 2000 averaged $30.20 a barrel, the highest level since 1983, and well above the 1999 average of $19.25. Traders also saw support for the oil price from the Opec basket of seven crude oils which stood at $21.75 a barrell on 29 December 2000. That was the seventh day the price stayed below a preferred range of $22-$28 a barrell. Under an Opec price stability measure, output will be cut by 500,000 barrels a day if the basket price stay below $22 for more than 10 days."

  • BBC - WW2 People's War
    • "I left [school] at Easter 1938. As soon as I had left school, my Father insisted that I went to work for my Uncle. My wages were 5 shillings per week plus board & lodgings"
