The software in the middle—Letter from the Editors-in-Chief

Welcome to the second issue of JISA.As Editors-in-Chief, we have been delighted by the response to the inaugural issue that included some quite outstanding papers from major figures in the field on Internet Services and Applications.We aim to maintain this high standard and, through this, get JISA quickly established as one of the major publication venues for work in this field.To achieve this goal, we need your help and encourage you to submit high quality manuscripts to us for consideration.In return, we promise fast turnaround in terms of reviewing times.This second issue features four papers, including three papers that together form a special issue on the topic of middleware.The first paper, "A Search Engine for the Global PKI" by Paul Rabinovich, focuses on the problem of managing Public Key Infrastructures.The author seeks to offer a service for global PKI matching, what Google does for the Web, offering a unified view of the global PKI and supporting such functions as certificate discovery and certification revocation status lookup.These are important issues in being able to offer practical solutions for PKI management in large-scale distributed systems.Congratulations to Paul on being our first accepted author
