In following up on a researcher request for supplemental material posting on a project web site in coordination with a published journal article, we’ve discussed establishing a simplified path such as (http://pal.lternet.edu/suppl) that can be created as a physical location initially and shifted to a virtual pointer as our web structure matures. The idea is to provide directories tied then to the related database (in this case the bibliographic database with its attendant unique identifier (or LTER contribution#, ie http://pal.lternet.edu/suppl/biblio279)

At the following link

,
the use of the Digital Object Identifier is summarized as follows:

“The digital object identifier (DOI) may be used to cite and link to electronic documents. The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly ?Articles in press? because they have not yet received their full bibliographic information. The correct format for citing a DOI is shown as follows (example taken from a document in the journal Physics Letters B): doi:10.1016/j.physletb.2003.10.071″

“When you use the DOI to create URL hyperlinks to documents on the web, they are guaranteed never to change. ”

The idea of ‘guaranteed never to change’ brings forward the question of the length of ‘forever’ in contemporary organizational life or in internet timeframes and prompts two thoughts: 1) the lternet virtual pointer has an advantage of stability in addition to the original strengths of network identity and geographic indendence; 2) it might be worthwhile inquiring at the sio library about their insights or plan with respect to this type request.
