DESCRIPTION
The schema extension
deployment defines the deployment table which tracks the possible
data availability of a station. Development was driven by the need to produce a Virtual
Network Definition (VND) file for the DMC. This schema incorporates time values for the
actual first and last data available, the equipment installation and removal, an operational
time/endtime range based on certification criteria, the virtual net code, the snet, and the
sta.
FIELDS
-
vnet
The virtual network code. Per DMC convention, the vnet starts with an "_".
For instance, _US-TA, _GSN-BROADBAND, _REALTIME. See
http://www.iris.edu/news/newsletter/vol6no2/page1.htm or
http://www.iris.edu/vnets for more information.
-
snet
The SEED network code. Normally this is the two character network code for the station, i.e.
AZ, BK, CI, TA, US.
-
sta
The three to five character station code.
-
time
Time of first data available for external users.
This is normally the time of the first sample recorded in a wfdisc at the data center.
Note this date should not be earlier than the equip_install, but could be earlier
than the cert_time.
-
endtime
Time of last data available. This is normally the endtime in the wfdisc for the last
sample recorded at the data center.
-
equip_install
Time seismic equipment was first installed.
-
equip_remove
Time seismic equipment was removed. This can be left null if the equipment remains
on-site but is no longer part of a described virtual network. See adoption(5).
-
cert_time
For ANF purposes, the time that the metadata was first passed along after passing basic
verification checks or the time that data started flowing to external users.
This can also be considered as the time which the station first
belongs to the vnet.
-
decert_time
For ANF purposes, the time that the closing metadata was passed along or the time that
the station was removed from external data import. This can also be
considered as the time which the station no longer belongs to the vnet
This could be the same or later than endtime and could be the same or later than
equip_remove.
-
pdcc
Primary data center. This means something to the DMC in terms of data availability and
available software. Despite being the primary collection point for TA data, the ANF is not
considered a PDCC, and IRIS DMC is filled in for this field instead.
-
sdcc
Secondary data center.
-
lddate
Modification time.
BUGS AND CAVEATS
The original deployment extension schema used a shorter field
net instead of
vnet.
You will need to convert any older version deployment tables to this new version. I have provided
a script called
convert_deployment(1) to do this.
