OGF colleagues, FYI, the editors of the Journal of Grid Computing requested a special issue some time ago on cloud computing federation, API development and associated topics, which has now been recruited, assembled, reviewed extensively and published. Many of the articles in this issue may be of interest to members of the OGF community, some of whom are authors. Thanks very much to my hard-working co-editor for this issue, Gabor Kecskemeti, for carrying much of the weight of assembling it and communicating on many associated details with the reviewers and authors. Hope you will find the results to be of interest. If you have ideas for other special issues and topics, please communicate with the JOGC contacts as listed on the web site.
