Installation
From source code:
::
python setup.py install
Context url

^^^^^^^^^^^^^^^^^^^^^^
Instantaneous temperature at 2m above ground measured by fixed station at
longitude 12.12345, latitude 44.67890 in network "agrmet"::
/-/1212345,4467890/agrmet/254,0,0/103,2000,-,-/B12101
Web interface
A simple web interface is available at the base dir /
.
Web API
The response is in GeoJSON
format (http://geojson.org/)::
{
"type": "FeatureCollection",
"features": [
{
"geometry": { "type": "Point", "coordinates": [ 11.95861, 44.36013 ] },
"properties": {
"ident": null,
"lon": 1195861,
"lat": 4436013,
"network": "locali",
"trange_pind": 254,
"trange_p1": 0,
"trange_p2": 0,
"level_t1": 103,
"level_v1": 2000,
"level_t2": null,
"level_v2": null,
"bcode": "B12101"
}
},
{
...
}
]
}
The services can extend the property list (e.g. datetime
and value
for timeseries services).
The services support the JSONP
format, using the GET
parameter callback=NAME
.
Summaries
^^^^^^^^^
::
/*/*/*/*/*/*/summaries
/*/*/NETWORK/*/*/*/summaries
/-/COORDINATES/NETWORK/*/*/*/summaries
/IDENT/*/NETWORK/*/*/*/summaries
/*/*/NETWORK/TIMERANGE/LEVEL/BCODE/summaries/YEAR/MONTH
/*/*/NETWORK/TIMERANGE/LEVEL/BCODE/summaries/YEAR/MONTH/DAY
The features have a datetime
property: if the date extremes are available,
then is an array with min and max date. Otherwise, is null
.
Time series
^^^^^^^^^^^
::
/IDENT/COORDINATES/NETWORK/TIMERANGE/LEVEL/BCODE/timeseries/YEAR
/IDENT/COORDINATES/NETWORK/TIMERANGE/LEVEL/BCODE/timeseries/YEAR/MONTH
/IDENT/COORDINATES/NETWORK/TIMERANGE/LEVEL/BCODE/timeseries/YEAR/MONTH/DAY
The features have a datetime
and value
property.

Spatial series
^^^^^^^^^^^^^^
::
/*/*/NETWORK/TIMERANGE/LEVEL/BCODE/spatialseries/YEAR/MONTH/DAY/HOUR
The features have a datetime
and value
property.
Station data
^^^^^^^^^^^^
::
/-/COORDINATES/NETWORK/-,-,-/257,-,-,-/*/stationdata
/IDENT/*/-,-,-/257,-,-,-/*/stationdata
The features have a value
property.
Simple web server
The borinud.ws
module has a simple web server tool::
python -m borinud.ws --dsn=sqlite://...
Or run python -m borinud.ws --help
for more options.
Deployement under Apache with mod_wsgi
The Apache configuration is something like this (see
http://code.google.com/p/modwsgi/ for details)::
<VirtualHost *:80>
WSGIDaemonProcess borinud user=www-data group=www-data processes=10 threads=1
WSGIScriptAlias /borinud /var/www/borinud/app.wsgi
</VirtualHost>
And you must create the file /var/www/borinud/app.wsgi
::
import borinud.ws
import borinud.db
dba_dsn = "sqlite:/dev/shm/borinud.db"
application = borinud.ws.app
application.config.db = borinud.db.DballeDB(dba_dsn)
Database
borinud
reads data from a DB-All.e
database::
from borinud.db import DballeDB
# Create a DB-All.e database
db = DballeDB("sqlite:mydatabase.sqlite")
# Load the summary
summary = db.query_summary(dballe.Record())
# Load temperature data
data = db.query_data(dballe.Record(var="B12101"))
Caching the summary
^^^^^^^^^^^^^^^^^^^
If the database has a lot of data, loading the summary could be a bottle neck.
You can dump the summary in a file and use it as a preemptive cache::
import dballe
from borinud.db import DballeDB, SummaryCacheDB
# Create a DB-All.e database with cached summary
db = SummaryCacheDB(DballeDB("sqlite:mydatabase.sqlite"), "/var/lib/borinud-summary.json")
# Dump cached summary in /var/lib/borinud-summary.json.
# NOTE: the cached summary must be written before using it
db.write_cached_summary()
# Load the summary
summary = db.query_summary(dballe.Record())
# Load temperature data
data = db.query_data(dballe.Record(var="B12101"))
# Update the summary cache
db.write_cached_summary()
The web service can use a summary cache::
python -m borinud.ws --dsn=sqlite:mydatabase.sqlite --cached-summary=/var/lib/borinud-summary.json
And the cache can be updated by a simple script::
#!/usr/bin/python
# cacheupdater.py
from borinud.db import DballeDB, SummaryCacheDB
db = SummaryCacheDB(DballeDB("sqlite:mydatabase.sqlite"), "/var/lib/borinud-summary.json")
db.write_cached_summary()
This script can be executed by cron
to update periodically the summary::
*/10 * * * * python cacheupdater.py
.. note::
When the web service starts, the summary must be already created::
python cacheupdater.py && python -m borinud.ws --dsn=sqlite:mydatabase.sqlite --cached-summary=/var/lib/borinud-summary.json
