Hi, Alex . What's the Mabinogion, please?

I admit that it had not occurred to me to consider these two characters' names as being oppositional to one another. Here's what Gurunet has about each:
da·ta (dā'tə, dăt'ə, dä'tə)
pl.n. (used with a sing. or pl. verb)

1. Factual information, especially information organized for analysis or used to reason or make decisions.
2. Computer Science. Numerical or other information represented in a form suitable for processing by computer.
3. Values derived from scientific experiments.
4. Plural of datum (sense 1).
[Latin, pl. of datum. See datum.]

USAGE NOTE The word data is the plural of Latin datum, “something given,” but it is not always treated as a plural noun in English. The plural usage is still common, as this headline from the New York Times attests: “Data Are Elusive on the Homeless.” Sometimes scientists think of data as plural, as in These data do not support the conclusions. But more often scientists and researchers think of data as a singular mass entity like information, and most people now follow this in general usage. Sixty percent of the Usage Panel accepts the use of data with a singular verb and pronoun in the sentence Once the data is in, we can begin to analyze it. A still larger number, 77 percent, accepts the sentence We have very little data on the efficacy of such programs, where the quantifier very little, which is not used with similar plural nouns such as facts and results, implies that data here is indeed singular.

lore1 (lôr, lōr)
n.

1. Accumulated facts, traditions, or beliefs about a particular subject. See synonyms at knowledge.
2. Knowledge acquired through education or experience.
3. Archaic. Material taught or learned.
[Middle English, from Old English lār.]

lore2 (lôr, lōr)
n.
The space between the eye and the base of the bill of a bird or between the eye and nostril of a snake.

[Latin lōrum, thong.]

This def. of lore would seem to give as much credibility as data. The concept of lore as accumulated knowledge would have been particularly apt, for a machine that was designed to contain everything about all known cultures. The term folklore has come to carry the almost-automatic baggage of disbelief; but I don't think that applies to Lore.
