RIA, the Institutional Repository of the University of Aveiro (UA), is an information system that captures and preserves the research outputs of UA scientific community and make them available over the Web, increasing visibility and impact. It ensures open access to the full text version of documents whenever the authors authorize it.

The Repository is structured in Communities that match the departments, services, polytechnic schools, research units and associated laboratories of the University. Within each community, the RIA is organized into collections, which correspond to document types. Each collection can contain an unlimited number of documents.


Browse allows you to go through a list of items in some specified order:

Publication date: through a list of all documents in the Repository, in chronological order.

Author: through an alphabetical list of all authors of documents in the Repository.

Advisor: through an alphabetical list of all advisors of documents in the Repository.

Title: through an alphabetical list of all the titles of documents in the Repository.

Subject: through an alphabetical list of keywords assigned to documents in the Repository.

Document type: through a list with the assigned document type in the Repository.

Access type: through a list with the levels of access to documents in the Repository.

You may sign on to the system if you:

To search all of Repository, use the search box at the top of the navigation bar on the right.

search RIA

Some search hints:

What is searched in the general search 
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.
In RIA the full-text searching is enabled, so the text you entered will also be searched against the full-text of all archived documents. 

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"

Use an asterisk (*) after a word stem to get all hits having words starting with that root, for example:
Sele*   will retrieve selects, selector, selectman, selecting.

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, for example:
"organizational change"

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.


The RIA content is organized into communities that match the university departments, services, polytechnic schools, research units and associated laboratories. Within each community, the RIA is organized into collections, which correspond to document types. Each collection can contain an unlimited number of documents.

Each community has its own entrance page, which can contain information, news and links according to the interests of that community, as well as a list of collections within the community.

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 DSpace Supported Formats.

Uploaded File

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:

  • Click on the filename. This will download the file in a new browser window, so that you can check the contents.
  • Compare the file checksum displayed here with the checksum you calculate.

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.


DSpace 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 DSpace-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 DSpace reports.

SUBMIT: Verify Submission top of submit top
