Make a Topographic Map Build your own mountain of clay or Play-Doh ®, then make a topo map of it. Then read about the largest structure ever to fly in space and how it made a topo map of the whole world. Teaches how topo maps are made and how to read them. Explains how radar is used from space to make topo maps of Earth. From MERLOT - 10 Most Recent Materials on April 8, 2006 at 7:30 a.m..


Space Interferometry Mission (SIM) Website How big is the universe? How old is it? Are there other planets like Earth out there among the stars? We have asked these questions around campfires and in the halls of universities for centuries. Today, we know that the answers lie hidden in the positions and distances of the stars and galaxies. And each time scientists have measured these positions and distances with greater accuracy, they have gained a wealth of new understanding. The Space Interferometry Mission (SIM), scheduled for launch in 2009, will determine the positions and distances of stars several hundred times more accurately th From MERLOT - 10 Most Recent Materials on April 8, 2006 at 7:30 a.m..

Measuring the Distance to the Sun Investigate the shape of the Earth's orbit based on the apparent changing size of the Sun. Is the orbit elliptical? Is it circular? Compare the difference in the Sun's diameter as measured from two points in the Earth's orbit and see what you discover! From MERLOT - 10 Most Recent Materials on April 8, 2006 at 7:30 a.m..


Soda Bottle Magnetometer Build a magnetometer for under $5.00 to monitor changes in the Earth's magnetic field inside your classroom. Some of these changes can be due to magnetic storms in space caused by space weather changes and solar storms. Join the Student Magnetometer Network (MagNet) and share your measurements. Detailed instructions, sample data, and tips are provided. From MERLOT - 10 Most Recent Materials on April 8, 2006 at 7:30 a.m..


OpenURL Framework for Context-Sensitive Services The OpenURL standard from the National Information Standards Organization (NISO) is a syntax to create web-transportable packages of metadata and/or identifiers about an information object. Such packages are at the core of context-sensitive or open link technology. The OpenURL is needed because conventional web links do not take into account the identity of the user: they take all users to the same target. This causes some problems. For example, when more than one institution provides access to copies of the same electronic article, the link from citation to full text should resolve to a copy From EdNA Online on April 8, 2006 at 2:56 a.m..


OpenSearch OpenSearch is a set of simple formats for the sharing of search results. Any website that has a search feature can make their results available in OpenSearch format. Other tools can then read those search results, for example, an aggregator that brings together search results from many websites. OpenSearch is an open format with a Creative Commons license. Rather than reinventing the wheel, it uses the simple and very popular syndication formats RSS and Atom, along with a document describing the search engine.

OASIS eXtensible Access Control Markup Language (XACML) TC The XACML Technical Committee will define a core XML schema for representing authorization and entitlement policies, also called XACML. It will identify bindings to existing protocols (e.g., XPath, LDAP), and define new protocols, if necessary, as means of accessing and communicating the policies. XACML is expected to address fine grained control of authorized activities, the effect of characteristics of the access requestor, the protocol over which the request is made, authorization based on classes of activities, and content introspection (i.e. authorization based on both the requestor and p From EdNA Online on April 8, 2006 at 2:30 a.m..
