Submit is the CNU IR function that enables users to add an item to CNU IR. The process of submission includes filling out information about the item on a metadata form and uploading the file(s) comprising the digital item. Each community sets its own submission policy.
My CNU IR is a personal page that is maintained for each member. This page can contain a list of items that are in the submission process for a particular member, or a task list of items that need attention such as editing, reviewing, or checking. In the future this page will also maintain information about personal services offered by CNU IR, such as e-mail notification when new items are added to a collection.
Edit Profile allows you to change your password.
About takes you to information about the CNU IR project and its development.
| SEARCH | top |
To search all of CNU IR, use the yellow search box at the top of the navigation bar on the left (or the search box in the middle of the home page)
To limit your search to a specific community or collection, navigate to that community or collection and use the search bar on that page.
CNU IR uses the Jakarta Lucene search engine. Here are some search hints:
What is searched in the general keyword search (yellow box)
The word(s) you enter in the search box will be searched against the title, author, subject abstract, series, sponsor and identifier fields of each item's record.If your site is enabled for full-text searching, the text you entered will also be searched against the full text of all archived documents. For more information on full-text searching please contact your CNU IR Administrator.
What is not searched - Stop Words
The search engine ignores certain words that occur frequently in English, but do not add value to the search. These are:"a", "and" , "are" , "as" , "at" , "be" , "but" , "by" , "for" , "if" , "in" , "into",
"is" ,"it" ,"no" , "not" , "of" , "on" , "or" , "such", "the" , "to" , "was"
Truncation
Use an asterisk (*) after a word stem to get all hits having words starting with that root, for example:
will retrieve selects, selector, selectman, selecting.
Stemming
The search engine automatically expands words with common endings to include plurals, past tenses ...etc.Phrase Searching
To search using multiple words as a phrase, put quotation marks (") around the phrase.
Exact word match
Put a plus (+) sign before a word if it MUST appear in the search result. For instance, in the following search the word "training" is optional, but the word "dog" must be in the result.
Eliminate items with unwanted words
Put a minus (-) sign before a word if it should not appear in the search results. Alternatively, you can use NOT. This can limit your search to eliminate unwanted hits. For instance, in the search
or
you will get items containing the word "training", except those that also contain the word "cat".
Boolean searching
The following Boolean operators can be used to combine terms. Note that they must be CAPITALIZED !
AND - to limit searches to find items containing all words or phrases combined with this operator, e.g.
will retrieve all items that contain BOTH the words "cats" and "dogs".
OR - to enlarge searches to find items containing any of the words or phrases surrounding this operator
will retrieve all items that contain EITHER the words "cats" or "dogs".
NOT - to exclude items containing the word following this operator, e.g.
will retrieve all items that contain the word "training" EXCEPT those also containing the word "cat".
Parentheses can be used in the search query to group search terms into sets, and operators can then be applied to the whole set, e.g.
| ADVANCED SEARCH | top |
The advanced search page allows you to specify the fields you wish to search, and to combine these searches with the Boolean "and", "or" or "not".
You can restrict your search to a community by clicking on the arrow to the right of the top box. If you want your search to encompass all of CNU IR, leave that box in the default position.
Then select the field to search in the left hand column and enter the word or phrase you are searching in the right hand column. You can select the Boolean operator to combine searches by clicking on the arrow to the right of the "AND" box.
Note: You must use the input boxes in order. If you leave the first one blank your search will not work.
| SUBJECT CATEGORY SEARCH | top |
A controlled vocabulary is a set of terms which form a dictionary of descriptions of particular types of content or subject matter. These are maintained by standards bodies in order to standardise the way that similar materials are categorised in archives. This aids searching by increasing the likelihood that the relevant materials will be returned by the user's search.
Filtering the category list will remove from the list any terms which do not match the filter. The remaining terms are any category or sub category which contains the filter term anywhere in the heirarchy. Expanding each category will show you which terms (or sub terms) did match the filter.
To search the archive items by the subject category, check as many boxes next to the categories as necessary, before clicking "Search...". The search will return all items that either match the categories selected exactly, or which are categorised underneath a higher level category. Clicking on the "+" next to the category will expand the tree to show you what refinements are available for your selected category.

| SUBMIT: Controlled Vocabulary | top of submit | top |
A controlled vocabulary is a set of terms which form a dictionary of descriptions of particular types of content or subject matter. These are maintained by standards bodies in order to standardise the way that similar materials are categorised in archives.
Accurately categorising material using a controlled vocabulary increases the likelihood that relevant results will be returned to users when searching individual or multiple archives.
To enter a controlled vocabulary term in the form, select "Subject Categories" from underneath the input field. This will open a window containing the available vocabularies. You may filter the vocabulary lists as described above in order to find the terms most relevant to your submission. Once you have found the term that you wish to enter, simply click on it, and it will be automatically entered into the submission form and the popup window will close. You may add as many subject category terms as you like into the form. Use "Add More" on the right to generate more input boxes.
Filtering the category list will remove from the list any terms which do not match the filter. The remaining terms are any category or sub category which contains the filter term anywhere in the heirarchy. Expanding each category will show you which terms (or sub terms) did match the filter.
| SUBMIT: Upload a File | top of submit | top |
There are two methods of entering the name of the file you wish to upload:
Type the full path and file name into the input box and then click on the "next" button in the lower right hand corner of the screen.
Click on the "browse" button and a window showing your files will appear. You can navigate through your directories and folders until you find the correct file to upload. Double-click on the file name you wish to upload, and the name will be entered into the input box.
Note: If you are using the Netscape browser, the default file type will be set to "HTML files", so you may not see all of your files. Here is how to see all your files:
On Windows and Macintosh computers, the window initially looks like this:
Click on the drop down arrow next to the "HTML Files" and select "All Files (*.*)":
On UNIX systems, the window initially looks like this:
Click to the right of the "*.html" in the top text box, and remove the ".html" with the backspace key, but leave the "*". Then, click on the "Filter" button at the bottom of the window. You will then see all of your files, like this:
Once the correct file name is in the input box, click on the "next" button to proceed.
If you specified at the beginning of the submit process that you had more than one file to upload for this item, you will see an input box marked "File Description". The information you provide here will help users to understand what information is in each file, for instance, "main article" or "images" or "computer program" or "data set". Enter file descriptions for each item, and click on the "next" button to proceed.
| SUBMIT: File Formats | top of submit | top |
To properly archive and give access to a file, we need to know what format it is, for example "PDF", "HTML", or "Microsoft Word". If the system does not automatically recognize the format of the file you have uploaded, you will be asked to describe it. If the format of the file appears in the list offered, click on it and then on "Submit". If you can't see the format in the list, click on "format not in list" and describe the format in the text box lower down on the page. Be sure to give the name of the application you used to create the file and the version of that application, for example "Autodesk AutoCAD R20 for UNIX".
For more information about file formats, see CNU IR Supported Formats.
After you have uploaded a file, check the information in the table to make sure it is correct. There are two further ways to verify that your files have been uploaded correctly:
If you're only uploading one file, click on "Next" when you're happy that the file has been uploaded correctly.
If you're uploading more than one file, click on the "Add Another File" button (this will appear if you checked "The item consists of more than one file" on the "Submit: Describe Your Item" page). When you are satisfied that all files for this item have been successfully uploaded, click on the "Next" button.
If you're uploading an HTML page with embedded files, click on the "Add Another File" button, and upload all files or bitstreams referenced in the html page. After all the are uploaded, in the column marked "Primary Bitstream", select the bitstream or file that is the index page or the top page for the web page. This will ensure that all of your embedded files will display properly on the HTML page. Then click on the "Next" button.
CNU IR generates an MD5 checksum for every file it stores; we use this checksum internally to verify the integrity of files over time (a file's checksum shouldn't change). You can use this checksum to be sure what we've received is indeed the file you've uploaded.
If you wish to verify the file using checksums, click "Show checksums" on the "Uploaded File" page. The CNU IR-generated MD5 checksum for every file we've received from you will show to the right of the filename. You will then need to use a local program to generate your own checksum for these files, and verify that your results match ours. On most UNIX-like systems (including Mac OS X), use md5sum. For instance, type "md5sum MYFILE" for every file you want to check; the summary should print on your screen. For Windows machines, MD5 tools are freely available: try md5 (from http://www.fourmilab.ch/md5/), or md5sum, available via the textutils package in Cygwin (http://www.cygwin.com/). All of these utilities will need to be run from a command-line, or terminal, window. The entire digest printed out when you run the md5 tool on your local copy of the file you're uploading should be exactly equal to what CNU IR reports.

| SUBMIT: Submission Complete | top of submit | top |
Now that your submission has been successfully entered into the CNU IR system, it will go through the workflow process designated for the collection to which you are submitting. Some collections require the submission to go through editing or review steps, while others may immediately accept the submission. You will receive e-mail notification as soon as your item has become a part of the collection, or if for some reason there is a problem with your submission. If you have questions about the workflow procedures for a particular collection, please contact the community responsible for the collection directly. You can check on the status of your submission by going to the My CNU IR page.
| HANDLES | top |
When your item becomes a part of the CNU IR repository it is assigned a persistent URL. This means that, unlike most URLs, this identifier will not have to be changed when the system migrates to new hardware, or when changes are made to the system. CNU IR is committed to maintaining the integrity of this identifier so that you can safely use it to refer to your item when citing it in publications or other communications. Our persistent urls are registered with the Handle System, a comprehensive system for assigning, managing, and resolving persistent identifiers, known as "handles," for digital objects and other resources on the Internet. The Handle System is administered by the Corporation for National Research Initiatives (CNRI), which undertakes, fosters, and promotes research in the public interest.
