Original Survey on Event Processing Languages

A few of us have been discussing*event processing languages (EPLs)*for a number of years, advocating*that SQL-like languages are appropriate for certain classes of CEP/EP problems, but not all.
Some*readers might recall that I published a draft survey on EPLs*to the Yahoo! CEP*Interest*group titled, (DRAFT) A Survey of Event Processing Languages (EPLs), October 15, 2006 (version 14).
A number of us CEP “grey beards” have consistently advocated that there are EPLs and analytics that are optimal for certain classes of event processing problems (and, in turn, there also are EPLs that are suboptimal for certain classes of event processing problems).
For readers who do not frequent the Yahoo! CEP group,*below here is*a link to a*copy of the original survey.

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
