DSV (distribution subvolume)
data communications subsystems, the Subsystem Programmatic Interface (SPI), the
Event Management Service (EMS), the Distributed Name Service (DNS), and
management programming interfaces for various Compaq subsystems.
DSV (distribution subvolume). The grouping in which Compaq releases software for
installation. Names are in the form Yxxxxzzz, where xxxx is the product number
and zzz is the release number—for instance, Y9110C20. See also ISV.
EDI forwarding. The onward transfer of a received EDIM to one or more recipients
determined by a forwarding EDI-UA, EDI-MS, or PDAU. The EDIM is forwarded
along with EDI notification requests contained within it. Any of the body parts within
the EDIM can be removed (wholly, not partially) when forwarding, except a forwarded
body part, which cannot be removed. Body parts that are removed when forwarding are
replaced with placeholders to indicate which type of body part was removed. Note that
the heading of an EDIM cannot be removed when forwarding.
EDI interchange. A trade document (such as a purchase order or invoice) in interchange
format. Currently, three formats are used widely: EDIFACT, ANSI12, and UNTDI. Of
these formats, EDIFACT is generally accepted worldwide as the defacto standard.
EDI messaging system (EDIMS). The means by which EDI messaging users communicate
with one another. The EDIMS can be viewed as consisting of functional objects which
interact. The central object, or core of the EDIMS, is the X.400 message transfer system
(MTS). The EDIMS uses MTS as an infrastructure for exchange of EDIMs. Each
EDIM is transferred as X.400 message content accompanied by an envelope (which
conforms to P1 protocol). The format of message content is similar to, but not the same
as, a P2 message. In addition to the MTS, the EDIMS also consists of numerous
peripheral objects of three kinds: EDI user agents (EDI-UAs), EDI message stores
(EDI-MSs), and EDI access units (EDI-AUs). These peripheral objects can be viewed
as access points for EDI users.
EDI messaging (EDIMG). The exchange of EDI messages (EDIMs) and EDI notifications
(EDINs). Both are information objects specified in CCITT Recommendation X.435.
EDI-MS (EDI message store). An X.400 MS that is tailored to better assist a single EDI-UA
to engage in EDI messaging.
EDI-UA (EDI user agent). An X.400 UA that is tailored to assist an EDIMS user to engage
in EDI messaging.
EDIFACT (Electronic Data Interchange for Administration, Commerce, Transport).
Trade document format developed in 1988 by the United Nations Economic
Commission of Europe (UNECE). EDIFACT is generally accepted worldwide as the
defacto standard for an EDI interchange.
EDIM (EDI message). Mechanism used to transfer an EDI interchange between originator
and recipient(s). An EDIM consists of a heading and body. The heading contains
information that describes the EDI interchange. The body consists of one primary body
part, and optionally, one or more additional body parts. The primary body part contains
