Explain the distinct functions of an academic article's publication date, repository upload date, Digital Object Identifier (DOI), and platform metrics (such as citation and read counts).

### Why this is right These details answer different questions: when the publisher issued the article, when a particular copy appeared on a platform, which work it is, and how much attention it has received. A repository upload can happen before or after publication, so its date does not replace the publication date. A DOI identifies and links to the work, while citation and read counts describe recorded engagement, not the work’s quality. ### The concept The **publication date** is the date the publisher officially issued the article. The **repository upload date** records when a copy was added to a particular online archive or platform; the same article can therefore have different upload dates in different places. A **Digital Object Identifier (DOI)** is a persistent, standardized identifier for a work, used to locate its record or link to it even if its web address changes. **Platform metrics** are counts recorded by a platform, such as how often the article has been cited or read there. They can indicate attention and reach, but counts may differ across platforms and do not directly measure research quality. | Detail | What it tells you | What it does not tell you | |---|---|---| | Publication date | When the publisher officially issued the article | When a repository copy was uploaded | | Repository upload date | When a copy was added to a particular platform | When the article was officially published | | DOI | Which work is being identified and how to locate it | When it was published or how influential it is | | Platform metrics | Recorded engagement, such as citations or reads | The article’s quality by themselves | ### What a good answer covers - Distinguishes the publisher’s publication date from a platform’s upload date. - Explains that a DOI is a persistent identifier and link for a work. - Describes citation and read counts as measures of recorded attention or reach. - Notes that metrics are not direct or absolute measures of research quality. ### Terms - **DOI**: Digital Object Identifier. A standardized, persistent identifier used to identify and locate a digital work. - **Repository**: An online archive that stores and provides access to scholarly works. - **Citation**: A reference to another work in academic writing; citation counts record how often a work is cited in the sources a platform tracks. - **Platform metrics**: Numerical measures collected by an online service, such as read or citation counts. ### Remember Dates tell you when an article was published or uploaded, a DOI identifies the work, and metrics count attention rather than quality.
