I want to add a word to the following list in my sentence to denote "up-to-date-ness" but am struggling to find the word:
...and addresses the accuracy, reliability, relevance, <up-to-date-ness> and completeness of data sources...
The best I can think of is "currency", but I'm not sure if there is a better term (that doesn't get confused with a money system).
There actually is a noun up-to-dateness.
From Merriam-Webster's definition of up-to-date:
up-to-dateness noun
In other words, the example sentence in the question is almost literally correct:
...and addresses the accuracy, reliability, relevance, up-to-dateness and completeness of data sources...
Merriam Webster lists currentness as a noun form for the adjective current. It isn't widely used, but would be readily understood and (unlike currency) not confused with something else.
"Age" can be a useful word in this context. We can certainly talk about the "age" of data. A downside is that it perhaps doesn't emphasize that the quality we presumably favor is how new the data is.
Data and news often described as being recent, and the word also fits nicely into that particular list because it starts with re-. Recent refers to something that happened not so long ago, and hence implies up-to-dateness. Moreover, recentness itself is a word which An American Dictionary the English Language by Noah Webster (1828) defines as meaning:
RE'CENTNESS, noun Newness; freshness; lateness of origin or occurrence; as the recentness of alluvial land; the recentness of news or of events
Granted, there is a slight difference between recent and up to date, in that hypothetically recent data could be inaccurate and hence detrimental to add to an update, but this minor distinction probably would not come into practical play very often.
Here is a relevant quotation which shows the word being used similarly from *Fusionplex: Resolution of Data Inconsistencies in the Integration of Heterogeneous Information Sources, by Amihai Motro and Philipp Anokhin (2006):
Fusionplex is a system for integrating multiple heterogeneous and autonomous information sources that uses data fusion to resolve factual inconsistencies among the individual sources. To accomplish this, the system relies on source features, which are meta-data on the merits of each information source; for example, the recentness of the data, its accuracy, its availability, or its cost.
up to the minute TFD an idiom
Describing something that is as current as is possible. The phrase is sometimes hyphenated when used as a modifier before a noun.
As in:
Which news station do you think will have the most up-to-the-minute news on the hurricane?
