Web Portal to Access Server Files

Introduction

The Myra-pm software accesses your files and folders from the web, kind of like Dropbox or Box.

Photo galleries are dynamically created and cached as needed. Documents can be uploaded or downloaded either from the web or from the backend file shares. HTML documents can be created and edited from the web.

  • Slides are also automatically created as needed and cached.
  • Slides can be rotated without changing the original picture.
  • An image magnifier can be shown over the slides.

  • Editors can restrict which kind of files can be uploaded to a folder.
  • Emailed notifications can be sent when someone does upload a file to a folder.
  • The portal can be set up as a read-only web site to be managed only by the sysadmin.
  • The portal can be set up to be managed through the web by editors who are members of the "editors" group.
  • The portal can be set up to use a central LDAP server to determine a user's read and write privileges.
  • Editors can be restricted to being only editors of specified subfolders.
  • Editors can annotate folders by adding headers and footers to the file list.
  • Editors can create new documents, and upload files, and remove documents.
  • Deleted documents and files altered from the web are archived so previous versions of a file could be retrieved if needed.
  • Shortcuts to other files and folders can be made.
  • Web documents are edited "in place" over the web by editors.
  • New web documents are created from site-specific templates.
  • The appearance of web documents and folders is determined by themes.

  • Themes can be chosen by the web user if allowed.

Overview

There are four primary pieces to the Myra portal software.

myra
The myra directory holds the web site programs. This is the main directory of the web programs.
myra-local
The myra-local directory holds the local site's web programs and files. These are mostly templates and images that will not be touched when Myra-pm is updated.
myra-support
This directory contains the support scripts for the web site programs in the myra directory. This directory needs to be located outside of the web directory. Some of the scripts interface to the Linix sudo facility.
apache
The apache web server is listed here because there are settings that need to be installed. Its mod_autoindex facility is used to automatically list folder contents on the site so it's best to set up the site's security there.
