Axis

arko — Tue, 27 Nov 2007 13:41:00 -0800

AXIS allows to create very fast a web service based on SOAP. It provides tools to create from your code WSDLs (Schemas used in web services). Additionally it helps you to deploy the service in a server like Tomcat. In about 1- 3 hours you can a simple service running.

Major problems are with the classpath and having it available outside the firewall (if you are behind one). Make sure that is is properly configured.

IEEE 1451

graybeal — Wed, 28 Nov 2007 07:03:00 -0800

There is no strong center of the IEEE 1451 web presence, but a google search on "IEEE 1451" finds many interesting and useful references. IEEE 1451 is a comprehensive, extremely detailed standard for describing sensors and actuators (together, "transducers"). From the web site:

Keyhole Markup Language: KML

luisBer — Wed, 28 Nov 2007 07:03:00 -0800

Keyhole Markup Language, or KML, is a simple but powerful file format for displaying geographic data in an earth browser, such as Google Earth or Google Maps. Increasingly, people are starting to use it in their own applications to represent geographic data.

NcML: NetCDF XML

ngalbraith — Wed, 28 Nov 2007 05:57:00 -0800

From the website:

NcML is an XML representation of netCDF metadata. It is similar to the netCDF CDL (network Common data form Description Language), except that it uses XML syntax. An NcML file essentially contains the same header information one gets from a netCDF file with the "ncdump -h" command.

NetCDF Dataset Discovery Attribute Convention

ngalbraith — Fri, 11 Jan 2008 19:21:00 -0800

Standard attributes describe a NetCDF dataset to facilitate data discovery. The attributes parallel the "digital library metadata" defined in the THREDDS catalog specification.

Attributes are used to add information inside the NetCDF file, while THREDDS catalog metadata adds information external to the NetCDF file. THREDDS tools will use these attributes for extracting metadata from datasets, and exporting to Dublin Core, DIF, ADN, FGDC, ISO 19115 etc. metadata formats.

OBIS Schema

kstocks — Wed, 28 Nov 2007 07:03:00 -0800

The OBIS schema is the content standard used by OBIS, the Ocean Biogeographic Information System. It represents an extension of the Darwin Core Version 2. It is designed for marine biodiversity data, specifically to record the capture or observation of a particular species or other taxonomic group at a particular location. It can also be applied to museum specimen data.

RDF model: triples triples triples

RDF triples are like sentences, composed of subject, predicate and object. The RDF triples are sometimes also known as resource, property, value triples.

So, informally a triple can be as follows, corresponding to the concept that "temperature is of type parameter":

SensorML

graybeal — Wed, 28 Nov 2007 07:03:00 -0800

A mature and active specification. The model is presented in several different forms (graphical, XML schema), with lots of documentation, and so should be useful to most developers.

The following description was taken from the web site on 2004.11.20.

Purpose: SensorML provides the models and XML schema encoding for defining the geometric, dynamic, and observational characteristics of a sensor. The purpose of SensorML is:

TransducerML

graybeal — Wed, 28 Nov 2007 07:03:00 -0800

TML is a digital data structure that permits streaming and is used to exchange data between a sensor and a processor. TML is an XML based specification that describes how to capture and time tag sensor data. It also includes a complete description of the data. Since TML is self-contained, a TML enabled processor is able to process data from any sensor without any additional information.
