Papyrus Oxyrhynchus 261

Papyrus Oxyrhynchus 261 (P. Oxy. 261 or P. Oxy. II 261) is a fragment of an Appointment of a Representative, in Greek. It was discovered in Oxyrhynchus. The manuscript was written on papyrus in the form of a sheet. It is dated to 55-56. Currently it is housed in the British Library (Department of Manuscripts, 792) in London.[1]

Description

The document was written by a woman, named Demetria. Demetria appoints her grandson Chaeremon to act as her representative in a lawsuit which was pending between herself and a certain Epimachus. The measurements of the fragment are 246 by 158 mm. The text is written in an uncial hand.[2]

It was discovered by Grenfell and Hunt in 1897 in Oxyrhynchus. The text was published by Grenfell and Hunt in 1899.[2]

gollark: Basically, if I want to run a search it just goes `SELECT * FROM page_tokens WHERE token = 'one token in search query'` or something like that, and it now has a list of pages with the right token, and SQLite can execute this query relatively fast.
gollark: I mean, as far as I can tell there isn't really a faster *and* more storage-efficient way to do search than the inverted-index page_tokens thing.
gollark: ```sqlCREATE TABLE crawl_queue ( id INTEGER PRIMARY KEY, url TEXT NOT NULL UNIQUE, lockTime INTEGER, added INTEGER NOT NULL, referrer TEXT);CREATE TABLE pages ( id INTEGER PRIMARY KEY, url TEXT NOT NULL UNIQUE, rawContent BLOB NOT NULL, rawFormat TEXT NOT NULL, textContent TEXT NOT NULL, updated INTEGER NOT NULL);CREATE TABLE page_tokens ( id INTEGER PRIMARY KEY, page INTEGER NOT NULL REFERENCES pages(id), token TEXT NOT NULL, weight REAL NOT NULL);CREATE TABLE links ( id INTEGER PRIMARY KEY, toURL TEXT NOT NULL, fromURL TEXT NOT NULL, lastSeen INTEGER NOT NULL, UNIQUE (toURL, fromURL))```Here is the database.
gollark: To be fair, the text content field isn't that necessary, as for search it uses the page_tokens table anyway and it can be rebuilt from the HTML if I need it.
gollark: The frequency of every word *must* be stored for quick (O(log n) time or something) search, the raw HTML or at least might be needed if I come up with a better way to weight frequency or something, the links are useful for (future) better search ranking algorithms.
