<div dir="ltr">Baltimore, MD - February 16, 2017 - The National Information Standards
Organization (NISO) is pleased to announce the formal publication of an
updated version of the <a href="http://www.niso.org/standards/z39-99-2017/">ResourceSync Framework Specification (ANSI/NISO Z39.99-2017)</a>.
Approved by the American National Standards Institute (ANSI), this 1.1
revision improves a web standard that details various capabilities that a
server can implement to allow third-party systems to remain
synchronized with evolving resources. Such synchronization is important
in the current landscape where Web-based content-not only the metadata
about the content-is constantly changing. <br>
<br>
ResourceSync was first published as ANSI/NISO Z39.99 in 2014. The
standard, also known as the ResourceSync "core" specification, offers a
range of easy-to-implement capabilities that a server may support in
order to enable remote systems to remain more tightly in step with its
evolving resources. It also describes how a server should advertise the
facilities it supports, and presents plentiful examples and use cases
that offer guidance for implementation. The recent revisions to the
standard, which is pull-based, reflect changes to fix problems related
to the conflation of last modification date of a resource and the
datetime of notification of a change to the resource.<br>
<br>
"Web resources and collections of web resources are continually evolving
and, in many cases, applications that want to leverage these resources
need to be confident that the data they use is the most up-to-date
available," says Herbert Van de Sompel, Scientist, Los Alamos National
Laboratory, OAI Executive, and Co-chair of the ResourceSync Working
Group. "Our revision to the ResourceSync core specification strengthens a
standard that addresses a core need for resource discovery and
synchronization across different systems in domains such as scholarly
communication, cultural heritage, and education. ResourceSync is very
modular in design and is based on the HTTP and Sitemap protocols to
ensure easy uptake in many applications, including-but not limited
to-timely sharing data from different types of repositories. Also,
associated optional specifications provide extensions to the ANSI/NISO
ResourceSync core. These include specifications to support archives of
synchronization information and push-based change notification."<br>
<br>
"One of NISO's core functions is keeping our standards reliable and up
to date," explains NISO Executive Director Todd Carpenter. "We're
grateful to the ResourceSync working group whose efforts make this
publication more valuable to those whose work relies on seamless
updating of information. NISO also strives to create guidelines that are
adaptable at various levels and for various needs. ResourceSync's
modular capabilities can be customized for specific local or community
requirements, making them useful for the range of institutions that use
our standards." <br>

ANSI/NISO Z39.99-2017 standard are available on the NISO website at <a href="http://www.niso.org/workrooms/resourcesync/">www.niso.org/workrooms/resourcesync/</a>.<br>
