<!-- Release Announcement --><h2 id="announcement">Release anouncement for V1.2</h2>
<p>
2011-02-16 16:28:59 +00:00
The VIVO 1.2 release incorporates major changes throughout the application -
notably a new templating system to support more versatile page rendering, plus
improvements to address scalability. The release also features a new personal
visualization option covering grants as well as publications. The VIVO Harvester
library has also been significantly improved and expanded in scope for its 1.0
release through the VIVO SourceForge project at
<a href="http://sourceforge.net/projects/vivo">http://sourceforge.net/projects/vivo</a>.
</p>
<h4>Templating system for page generation, navigation, and theming</h4>
<p>
2011-02-16 16:28:59 +00:00
A fresh installation of VIVO 1.2 looks strikingly different, with the introduction
of a new default theme which takes advantage of the navigation and browse features
delivered by the templating system. Individual pages now offer inline navigation to
streamline viewing of expanded personal and organizational profiles, as well as
improved content layout and organization. New browse controls on the home page and
menu pages help to provide an immediate overview of the size and range of content
and quick access down to the individual person, organization, research feature, or
event.
</p>
<h4>Storage model</h4>
<p>
2011-02-16 16:28:59 +00:00
While server memory capacity has increased significantly in recent years, VIVO's reliance
on in-memory caching of RDF data had put limits on the ultimate scalability of VIVO instances
and potentially increased the cost of servers required to support VIVO.
</p>
<p>
2011-02-16 16:28:59 +00:00
With version 1.2, VIVO has been converted to optionally use Jena's SPARQL database (SDB)
subsystem. SDB significantly reduces the baseline memory footprint, allowing VIVO installations
to scale well beyond what has previously been possible.
</p>
<h4>New visualizations</h4>
<p>
2011-02-16 16:28:59 +00:00
Visualizations of networks of co-authors are now complemented by visualizations of co-investigators
on grants, with similar interactivity and options for export as images or data.
</p>
<h4>Ontology</h4>
<p>
VIVO 1.2 includes a new ontology module representing research
resources including biological specimens, human studies, instruments,
organisms, protocols, reagents, and research opportunities. This module
is aligned with the top-level ontology classes and properties from the
NIH-funded <a href="https://www.eagle-i.org/home/">eagle-i Project</a>.
</p>
<h3>Associated VIVO releases</h3>
<h4>VIVO Harvester</h4>
<p>
2011-02-16 16:28:59 +00:00
The Harvester development team is releasing version 1.0 of the VIVO Harvester library shortly
following the release of VIVO 1.2. The Harvester is an extensible data ingest and updating
framework with sample configurations for loading PubMed publication, grants, and human resources
data. Pre-release versions of the Harvester are available at
<a href="http://sourceforge.net/projects/vivo">http://sourceforge.net/projects/vivo</a>.

<h3 id="required_software">I. Install required software </h3>
<p>
Before installing VIVO, make sure that the following software is
installed on the desired machine:
</p>
<ul>
<li>
Java (SE) 1.6 or higher, <a href="http://java.sun.com">http://java.sun.com</a>
(Not OpenJDK)
</li>
<li>
Apache Tomcat 6.x or higher, <a href="http://tomcat.apache.org">http://tomcat.apache.org</a>
</li>
<li>
Apache Ant 1.7 or higher, <a href="http://ant.apache.org">http://ant.apache.org</a>
</li>
<li>
MySQL 5.1 or higher*, <a href="http://www.mysql.com">http://www.mysql.com</a>
</li>
</ul>
<p>
2011-02-10 17:09:09 +00:00
Be sure to set up the environment variables for <code java_home="">JAVA_HOME</code>
and <code>ANT_HOME</code>
and add the executables to your path per
your operating system and installation directions from the software
2011-02-10 17:09:09 +00:00
support websites.
</p>
<p>
* Note that VIVO 1.2 will not run on older versions of MySQL that may have worked
with 1.1.1. Be sure to run VIVO 1.2 with MySQL 5.1 or higher. Using unsupported
versions may result in strange error messages related to table formatting or other
unexpected problems.
</p>
<h3 id="create_database">II. Create an empty MySQL database </h3>
<p>
Decide on a database name, username, and password. Log into your
MySQL server and create a new database in MySQL that uses <code>UTF-8
encoding</code>. You will need these values for Step IV when you
configure the deployment properties. At the MySQL command line you can
create the database and user with these commands substituting your
values for <code>dbname</code>, <code>username</code>, and <code>password</code>.
Most
of
the time, the hostname will equal <code>localhost</code>.
</p>
<pre> CREATE DATABASE dbname CHARACTER SET utf8;<br></pre>
<p>
Grant access to a database user. For example:
</p>
<pre> GRANT ALL ON dbname.* TO 'username'@'hostname' IDENTIFIED BY 'password';<br></pre>
<p>
Keep track of the database name, username, and password for Step
IV.
</p>
<h3 id="download_code">III. Download the VIVO Application Source
<br>
</h3>
<p>
Download the VIVO application source as either <code>rel-1.2.zip</code>
or <code>rel-1.2.gz</code>
file and unpack it on your web server:
<br>
<a href="http://vivoweb.org/download">http://vivoweb.org/download</a>
</p>
<h3 id="triple_store">IV. Choose Triple Store</h3>
<p>
VIVO 1.2 offers a choice of two triple store technologies: in-memory models backed by
2011-02-10 17:09:09 +00:00
Jena's legacy relational database store (RDB), and Jena's SPARQL database (SDB). RDB was
used by VIVO 1.1.1 and earlier. This mode offers fast response, but only by caching the
entire RDF model in the server's main memory. The memory available to VIVO limits the
number of RDF statements that may be stored.
</p>
<p>
SDB mode caches only a fraction of the RDF data in memory. Most queries are issued directly
against the underlying database. This allows VIVO installations to display data from large
RDF models while requiring only a small amount of server memory to run the application.
There is a tradeoff in response time: pages make take slightly longer to load in SDB mode,
and performance will depend on the configuration parameters of the database server.
Additionally, advanced OWL reasoning (not enabled by default in either mode) is not possible
in SDB mode. With SDB, only the default set of inferences (inferred rdf:type statements) are
generated, though they are generated as soon as data is edited rather than in a background process.
</p>
<p>
Though a VIVO installation may be switched back and forth between RDB and SDB mode by changing
a configuration property and redeploying the application, it is important to note that data
added in one mode will not typically appear in the other. The exception is when a system is
first switched from RDB mode to SDB mode. In this case, the data from the RDB store will be
automatically migrated to SDB.
</p>
<h3 id="deploy_properties">V. Specify deployment properties </h3>
<p>
At the top level of the unpacked distribution, copy the file <code>example.deploy.properties</code>
to a file named simply <code>deploy.properties</code>. This file sets
several properties used in compilation and deployment.
</p>
<p>
<em>Windows:</em>
For those installing on Windows operating
system, include the windows drive and use the forward slash "/" and not
the back slash "\" in the directory locations, e.g. <code>c:/tomcat</code>.
</p>
<p>
<em>External authentication:</em>
If you want to use an external
authentication system like Shibboleth or CUWebAuth, you will need to
set two additional properties in this file. See the section below
entitled <a href="#external_auth">Using an External Authentication
System with VIVO</a>.

</table>
<h3 id="deploy">VI. Compile and deploy</h3>
<p>
At the command line, from the top level of the unpacked
distribution directory, type:
</p>
<pre> ant all<br> </pre>
<p>
to build VIVO and deploy to Tomcat's webapps directory.
</p>
<h3 id="tomcat_settings">VII. Set Tomcat JVM parameters and security
limits</h3>
<p>
Currently, VIVO copies the contents of your RDF database into
memory in order to serve Web requests quickly (the in-memory copy and
2011-02-10 17:09:09 +00:00
the underlying database are kept in synch as edits are performed).
</p>
<p>
VIVO will require more memory than that allocated to Tomcat by
default. With most installations of Tomcat, the "setenv.sh" or
"setenv.bat" file in Tomcat's bin directory is a convenient place to
set the memory parameters.
<br>
For example:
</p>
<pre> export CATALINA_OPTS="-Xms2048m -Xmx1024m -XX:MaxPermSize=128m"<br> </pre>
<p>
This sets Tomcat to allocate an initial heap of 2048 megabytes, a
maximum heap of 1024 megabytes, and a PermGen space of 128 megs. 1024
megabytes is a minimum practical heap size for production installations
storing data for large academic institutions, and additional heap space
is preferable. For testing with small sets of data, 256m to 512m should
be sufficient.
</p>
<p>
If an OutOfMemoryError is encountered during VIVO execution, it can
be remedied by increasing the heap parameters and restarting Tomcat.
</p>
<p>
Security limits: VIVO is a multithreaded web application that may
require more threads than are permitted under your Linux installation's
default configuration. Ensure that your installation can support the
required number of threads by making the following edits to <code>/etc/security/limits.conf</code>:
</p>
<pre> apache hard nproc 400<br> tomcat6 hard nproc 1500 <br> </pre>
<h3 id="start_tomcat">VIII. Start Tomcat </h3>
<p>
Most Tomcat installations can be started by running <code>startup.sh</code>
or <code>startup.bat</code>
in Tomcat's bin directory. Point your
browser to "http://localhost:8080/vivo/" to test the application. If
Tomcat does not start up, or the VIVO application is not visible, check
the <code>catalina.out</code>
file in Tomcat's logs directory.
</p>
<h3 id="add_rdf">IX. Log in and add RDF data </h3>
<p>
If the startup was successful, you will see a welcome message
informing you that you have successfully installed VIVO. Click the "Log
in" link near the upper right corner. Log in with the <code>initialAdminUser</code>
username you set up in Step IV. The initial password for the <code>initialAdminUser</code>
account is "defaultAdmin" (without the quotes). On first login, you
will be prompted to select a new password and verify it a second time.
</p>
<p>
After verifying your new password, you will be presented with a
menu of editing options. Here you can create OWL classes, object
properties, data properties, and configure the display of data.
Currently, any classes you wish to make visible on your website must be
2011-02-10 17:09:09 +00:00
part of a class group, and there are a number of visibility and display
options available for each ontology entity. VIVO comes with a core VIVO
ontology, but you may also upload other ontologies from an RDF file.
</p>
<p>
Under the "Advanced Data Tools" click "Add/Remove RDF Data." Note
that Vitro currently works best with OWL-DL ontologies and has only
limited support for pure RDF data. You can enter a URL pointing to the
2011-02-10 17:09:09 +00:00
RDF data you wish to load or upload from a file on your local machine.
Ensure that the "add RDF" radio button is selected. You will also
likely want to check "create classgroups automatically."
</p>
<p>
Clicking the "Index" tab in the navigation bar at the top right of
the page will show a simple index of the knowledge base.
</p>
<p>
See more documentation for configuring VIVO, ingesting data, and
manually adding data at <a href="http://vivoweb.org/support">http://vivoweb.org/support</a>.
</p>
<h3 id="contact_email">X. Set the Contact Email Address (if using
"Contact Us" form)</h3>
<p>
If you have configured your application to use the "Contact Us"
feature in Step IV (<code>Vitro.smtpHost</code>), you will also need to
add an email address to the VIVO application.&nbsp; This is the email
2011-02-10 17:09:09 +00:00
to which the contact form will submit. It can be a list server or an
individual's email address.
</p>
<p>
Log in as a system administrator. Navigate to the "Site Admin"
table of contents (link in the right side of the header). Go to "Site
Information" (under "Site Configuration"). In the "Site Information
Editing Form," enter a functional email address in the field "Contact
2011-02-10 17:09:09 +00:00
Email Address" and submit the change.
</p>
<p>
2011-02-10 17:09:09 +00:00
If you set the <code>Vitro.smtpHost</code>
in Step IV and do NOT
2011-02-10 17:09:09 +00:00
provide an email address in this step, your users will receive a java
error in the interface.
</p>
<h3 id="tomcat_connector">XI. Set up Apache Tomcat Connector </h3>
<p>
It is recommended that a Tomcat Connector such as mod_jk be used to
ensure that the site address does not include the port number (e.g.
8080) and an additional reference to the Tomcat context name (e.g.
/vivo).
</p>
<p>
This will make VIVO available at "http://example.com" instead of
"http://example.com:8080/vivo"
</p>
<p>
Using the mod_jk connector allows for communication between Tomcat
and the primary web server. The <a href="http://tomcat.apache.org/connectors-doc/generic_howto/quick.html">Quick
Start
HowTo</a>
on the Apache site describes the minimum server
configurations for several popular web servers.
</p>
<p>
After setting up the mod_jk connector above, you will need to
modify the Tomcat's server.xml (located in <code>[tomcat root]/conf/</code>)
to
respond
to requests from Apache via the connector. Look for the
&lt;connector&gt; directive and add the following properties:
</p>
<pre> connectionTimeout="20000" maxThreads="320" keepAliveTimeout="20000"&nbsp; <br> </pre>
<p>
Note: the value for maxThreads (320) is equal to the value for
MaxClients in the apache's <code>httpd.conf</code>
file.
</p>
<p>
Locate the <code>&lt;Host name="localhost"...&gt;</code>
directive
and update as follows:
</p>
<pre>
&lt;Host name="localhost" appBase="webapps"<br>
DeployOnStartup="false"<br>
unpackWARs="true" autoDeploy="false"<br>
xmlValidation="false" xmlNamespaceAware="false"&gt;<br> <br>
&lt;Alias&gt;example.com&lt;/Alias&gt;<br>
&lt;Context path=""<br>
docBase="/usr/local/tomcat/webapps/vivo"<br>
reloadable="true"<br>
cookies="true" &gt;<br>
&lt;Manager pathname="" /&gt;<br>
&lt;Environment type="java.lang.String" override="false" <br>
name="path.configuration" <br>
value="deploy.properties"<br>
/&gt;<br>
&lt;/Context&gt;<br>
...
</pre>
<h3 id="pellet">XII. Configure Pellet Reasoner </h3>
<p>
This optional configuration step is only applicable to VIVO installations
running in RDB mode (See section <a href="triple_store">Choose Triple Store</a>
for details).
VIVO uses the Pellet engine to perform reasoning, which runs in the
background at startup and also when the knowledge base is edited. VIVO
continues serving pages while the reasoner continues working; when the
reasoner finishes, the new inferences appear. Inferred statements are
cached in a database graph so that they are available immediately when
VIVO is restarted.
</p>
<p>
By default, Pellet is fed only an incomplete view of your ontology
and only certain inferences are materialized. These include rdf:type,
rdfs:subClassOf, owl:equivalentClass, and owl:disjointWith. This mode
is typically suitable for ontologies with a lot of instance data. If
you would like to keep the default mode, skip to the next step.
</p>
<p>
To enable "complete" OWL inference (materialize all significant
entailed statements), open "vitro-core/webapp/config/web.xml" and
search for PelletReasonerSetup.
</p>
<p>
Then change the name of the listener class to
PelletReasonerSetupComplete. Because "complete" reasoning can be very
resource intensive, there is also an option to materialize nearly all
inferences except owl:sameAs and owl:differentFrom.
</p>
<p>
This is enabled by specifying PelletReasonerSetupPseudocomplete.
For ontologies with large numbers of individuals, this mode can offer
enormous performance improvements over the "complete" mode.
</p>
<p>
Finally, a class called
PelletReasonerSetupPseudocompleteIgnoreDataproperties is provided to
improve performance on ontologies with large literals where data
property entailments are not needed.

<h3 id="external_auth">XIII. Using an External Authentication System
with VIVO </h3>
<p>
</p>
<p>
VIVO can be configured to work with an external authentication
system like Shibboleth or CUWebAuth.
</p>
<p>
VIVO must be accessible only through an Apache HTTP server. The
Apache server will be configured to invoke the external authentication
system. When the user completes the authentication, the Apache server
will pass a network ID to VIVO, to identify the user.
</p>
<p>
If VIVO has an account for that user, the user will be logged in
with the privileges of that account. In the absence of an account, VIVO
will try to find a page associated with the user. If such a page is
found, the user can log in to edit his own profile information.
</p>
<h4>Configuring the Apache server</h4>
<p>
Your institution will provide you with instructions for setting up
the external authentication system. The Apache server must be
configured to secure a page in VIVO. When a user reaches this secured
page, the Apache server will invoke the external authentication system.
</p>
<p>
For VIVO, this secured page is named: <code>/loginExternalAuthReturn</code>
</p>
<p>
When your instructions call for the location of the secured page,
this is the value you should use.
</p>
<h4>Configuring VIVO</h4>
<p>
To enable external authentication, VIVO requires three values in
the <code>deploy.properties</code>
file.
</p>
<ul>
<li>
<h5>The name of the HTTP header that will hold the external user's
network ID.</h5>
<p>
When a user completes the authentication process, the Apache server
will put the user's network ID into one of the headers of the HTTP
request. The instructions from your institution should tell you which
header is used for this purpose.
</p>
<p>
You need to tell VIVO the name of that HTTP header. Insert a
line like this in the deploy.properties file:
</p>
<pre>externalAuth.netIdHeaderName = [the header name]</pre>
<p>
For example:
</p>
<pre>externalAuth.netIdHeaderName = remote_userID</pre>
</li>
<li>
<h5>The text for the Login button.</h5>
To start the authentication process, the user will click on a button in
the VIVO login form. You need to tell VIVO what text should appear in
that button.
<p>
Put a line like this in the deploy.properties file:
externalAuth.buttonText = [the text for your login button] For example:
</p>
<pre>externalAuth.buttonText = Log in using BearCat Shibboleth</pre>
<p>
The VIVO login form will display a button labelled "Log in using
BearCat Shibboleth".
</p>
</li>
<li>
<h5>Associating a User with a profile page.</h5>
<p>
If VIVO has an account for the user, the user will be given the
privileges assigned to that account.
</p>
<p>
In addition, VIVO will try to associate the user with a profile
page, so the user may edit his own profile data. VIVO will search the
data model for a person with a property that matches the Users network
ID. You need to tell VIVO what property should be used for matching.
Insert a line like this in the deploy.properties file:
</p>
<pre>selfEditing.idMatchingProperty = [the URI of the property]</pre>
<p>
For example:
</p>
<pre>selfEditing.idMatchingProperty = http://vivo.mydomain.edu/ns#networkId</pre>
</li>
</ul>
<h3 id="installation_check">XIV. Was the installation successful? </h3>
<p>
If you have completed the previous steps, you have good indications
that the installation was successful.
</p>
<ul>
<li>
Step VII showed that Tomcat recognized the webapp, and that the
webapp was able to present the initial page.
</li>
<li>
Step VIII verified that you can log in to the administrator
account.
</li>
</ul>
<p>
Here is a simple test to see whether the ontology files were
loaded:
</p>
<ul>
<li>
Click on the "Index" link on the upper right, below the logo.
You should see a "locations" section, with links for "Country" and
"Geographic Location." The index is built in a background thread, so on
your first login, you may see an empty index instead. Refresh the page
periodically to see whether the index will be populated. This may take
some time: with VIVO installed on a modest laptop computer, loading the
ontology files and building the index took more than 5 minutes from the
time that Tomcat was started.
</li>
<li>
Click on the "Country" link. You should see an alphabetical list
of the countries of the world.
</li>
</ul>
<p>
Here is a test to see whether your system is configured to serve
linked data:
</p>
<ul>
<li>
Point your browser to the home page of your website, and click
the "Log in" link near the upper right corner. Log in with the <code>initialAdminUser</code>
username you set up in Step IV. If this is your first time logging in,
you will be prompted to change the password.
</li>
<li>
After you have successfully logged in, click "site admin" in the
upper right corner. In the drop down under "Data Input" select "Faculty
Member(core)" and click the "Add individual of this class" button.
</li>
<li>
Enter the name "test individual" under the field "Individual
Name," scroll to the bottom, and click "Create New Record." You will be
taken to the "Individual Control Panel." Make note of the value of the
field "URI" - it will be used in the next step.
</li>
<li>
Open a new web browser or browser tab to the page <a href="http://marbles.sourceforge.net/">http://marbles.sourceforge.net/</a>.
In
the
pink box on that page enter the URI of the individual you
created in the previous step and click "open."
</li>
<li>
In the resulting page search for the URI of the "test
individual." You should find it towards the bottom of the page next to
a red dot followed by "redirect (303)." This indicates that you are
successfully serving linked RDF data. If the URI of the "test
individual" is followed by "failed (400)" you are not successfully
serving linked data.
</li>
</ul>
<p>
Finally, test the search index.
</p>
<ul>
<li>
Type the word "Australia" into the search box, and click on the
Search button.You should see a page of results, with links to countries
that border Australia, individuals that include Australia, and to
Australia itself. To trigger the search index, you can log in as a site
administrator and go to "http://your-vivo-url/SearchIndex".
</li>
</ul>
