* The AccountID from the `Owner` field.
**The first page of an Offer Directory** has a special ID: the higher 192 bits define the order book, and the remaining 64 bits define the exchange rate of the offers in that directory. (The ID is big-endian, so the book is in the more significant bits, which come first, and the quality is in the less significant bits which come last.) This provides a way to iterate through an order book from best offers to worst. Specifically: the first 192 bits are the first 192 bits of the SHA-512Half of the following values put together:
* The Book Directory space key (`B`)
* The Book Directory space key (`0x0042`)
