An anti-rival good meets the test of a
public good because it is non-excludable (freely available to all) and non-rival (consumption by one person does not reduce the amount available for others). However, it has the additional quality of being created by private individuals for common benefit without being motivated by pure
altruism
Altruism is the principle and moral practice of concern for the welfare and/or happiness of other human beings or animals, resulting in a quality of life both material and spiritual. It is a traditional virtue in many cultures and a core as ...

as anti-rivalrous: "It's not just that code is non-rival; it's that code in particular, and (at least some) knowledge in general, is, as Weber calls it, 'anti-rival'. I am not only not harmed when you share an anti-rival good: I benefit."

s. Leung (2006) quotes from Weber (2004), "Under conditions of anti-rivalness, as the size of the Internet-connected group increases, and there is a heterogeneous distribution of motivations with people who have a high level of interest and some resources to invest, then the large group is more likely,
all things being equal, to provide the good than is a small group."

allocation of any such data set is (near) universal availability.
# The value of many data sets increases with the number of users, because the shared knowledge tends to reduce the barriers to understanding and collaboration. This contrasts sharply with material goods, where consumption by one reduces and may eliminate the value to another.
Of course, this assumes that the data shared does not involve uses that would likely harm humans.
