Universal Character Set (UCS)
The international standard ISO 10646 defines the Universal Character Set (UCS). UCS is a superset
of all other character set standards. UCS also defines several methods for encoding a string of
characters as a sequence of bytes, such as UTF-8 and UTF-16.
Unicode Transformation Format-8 (UTF-8)
An octet (8-bit) lossless encoding of Unicode characters. MapXtreme supports UTF-8 only as
indicated in the workspace persistence schema.
Web Controls
An element on a web page that users interact with to send requests to the web server.
Web Map Service (WMS)
WMS is an OGC-compliant Web service that provides map images for use as layers in a mapping
application. MapXtreme provides a server implementation of WMS if you wish to host a WMS server
and a client for accessing any OGC-compliant (1.0.0, 1.1.0, or 1.1.1) WMS.
Web Feature Service (WFS)
An OGC-compliant Web service that offers geo-referenced map features for use in mapping
applications. MapXtreme provides an implementation of WMS Basic, a read-only service and a
client for accessing WMS servers.
Web server
A computer system that runs the Hypertext Transfer Protocol and Web Server software. A Web
server accepts URL-based HTTP requests from a Web user's browser and sends HTML pages back
to the browser. A Web server can manage one or many Web sites. A commercial server, for
example, would typically have many Web sites.
Workspace
An XML-based persistence file format that allows users of MapXtreme to share maps they have
created in a wide variety of environments. This is the file format that all future MapInfo products will
conform to. For more about creating workspaces, see
Chapter 23: Workspace Manager . For more
about the structure of workspaces, see Appendix C: Understanding the MapInfo Workspace .
XY Schema
A spatial schema that can be applied to a non-mappable to make it mappable. The table must
contain X and Y coordinate values, which the schema accesses to create a Geometry column for the
table.
