RSS (Really Simple Syndication)
RSS is a means of web content syndication using XML to represent lists of article summaries. It is most frequently used for time-varying sources of content, such as blogs and news feeds, but it also being adopted for periodicals and metadata exchange.
APA currently supports RSS feeds of PsycARTICLES® journal contents, both on an as-soon-as-published basis and as a random-access repository of machine-readable metadata.
There are a number of competing standards for the XML format used in RSS; APA has currently chosen "RSS 2.0" as it is simple, extensible, and has very widespread adoption; every mainstream reader and aggregator implementation should work with it.
Our PsycARTICLES feeds are enhanced with Dublin Core metadata fields providing certain elements not represented in RSS 2.0, such as article DOI.
The URL to obtain the HTML current-contents page of any PsycARTICLES journal is:
- http://content.apa.org/journals/[issn or jcode]
where jcode is APA's proprietary 3-letter code.
For example, the following two URLs both return the current-contents page for American Psychologist as HTML:
Following either of those with a '.rss' suffix returns the information as an RSS 2.0 XML file:
It is acceptable policy for the .rss URLs to be periodically polled for new articles, as they implement HTTP Conditional GET and so will not return results already cached in the client, saving bandwidth for you and us both. However given the frequency of updates (monthly, quarterly) it is best for polling to be limited to once per day per client.
