 \subsubsection{Indexing}
 \label{sec:indexing}
 
+\paragraph{Status quo ECHO}
+Currently indexing is not implemented on the ECHO server.
+
+\paragraph{Plan ECHO}
+
+\begin{enumeration}
+\item construct remote (141.14.236.86) index for each file at
+  per-change or daily intervals
+\item store indices locally in
+archimedes/data/db/PROJECT_NAME/CORPUS_NAME/WORK
+\item 2 progs on server 1. cgi: indexer 2. backend da_remote
+\item 2 progs on client 1. cgi: sendindex 2. backend getindex
+\item indexing transaction handled by two cgi scripts, one on the
+  server the other on the client [this is the 1st implementation bcs
+  its easiest and there are no port issues, but probably it'd be
+  better to have a separate port]. 
+\item client cgi: getindex -- sends 1.  list of files to index
+  2. uri to which xml notification of completion is to be sent. Upon
+  notification, activates backend prog that fetches and installs the
+  indices.  
+\item server cgi: indexer receives filelist and notification
+  addess. Activates backend that fetches files, indexes, places
+  completed indexes in a networked location, then sends xml
+  notification back to client. 
+\item single script provides backend access to indices 
+\item leave front-end issues like display, collection and navigation
+  to web-design programmers. Do only a  sample for now.
