vivo/doc/upgrade-1.1.txt
ejc12 5cdd24274c * reformated and retitled the notes to "Special notes about source files" 
* restructured Stella's ontology section and Jim's file storage section to provide verification info earlier. 

Questions: 
* Stella and Chris - could you provide feedback if the changes I made address your improvement recommendations? 
* Jim - is it still the "localhost" log where the error for the file system storage shows up in Tomcat? 
* Rebecca - in B.2 of the theme changes, is it 'a' or 'b', then 'c' for regardless? Sorry if I'm being dense.

Upgrading NIH VIVO
Steps to Upgrade from Release 1 Version 1.0 to Release 1 Version 1.1
This file provides a short description of the steps involved in upgrading your
installation of NIH VIVO from Release 1 Version 1.0 to Release 1 Version 1.1.
This and other documentation can be found at:
http://vivoweb.org/support
Installation:
If you need to do a fresh install, please consult the install.txt in this
directory.

I. Before Performing the Upgrade
Please read the bullet points below BEFORE beginning the upgrade.
The upgrade process is similar to the original install process with the following
exceptions:
* DO NOT reinstall MySQL or recreate the MySQL database. Please ensure that
you back-up the MySQL database.
* It is not necessary to add RDF data or reconfigure the Apache HTTP Server.
* First-time login of the administrator account will use the password
previously set, NOT the password in deploy.properties.
* The first time Apache Tomcat starts up after the upgrade, it will
initiate a process that modifies the knowledge base to align the data
with the revised ontology. See the section on "Ontology Changes"
below for more information.
* The first time Apache Tomcat starts up after the upgrade, it will
initiate a process that modifies the uploads directory (images), to align
the uploaded files with the revised file storage scheme. See the section
on "File Storage Changes" below for more information.
-------------------------------------------------------------------------------
II. The Upgrade Process
1. Ensure that backups are created of the Tomcat webapps directory, the
original source directory, the MySQL database, and the uploaded files
directory (images).
2. Download the new distribution file and unpack it into a new source
directory.
3. Create deploy.properties, using the same values as in your previous
installation.
4. Apply any changes you have made to the new source directory.
************* Special notes regarding source files ********************
This process assumes any changes made to the application were made in
the source directory and deployed, and were not made directly within
Apache Tomcat webapp.
In many cases, simply copying the modified files from your original
source directory will not work since the files on which they are based
have changed. It will be necessary to inspect the new source files and
add any changes to them at that time.
At a minimum it will be necessary to apply the Google Analytics Tracking
Code (GATC) to googleAnalytics.ftl in the theme:
[new_source_directory]/themes/[theme_dir]/templates/googleAnalytics.ftl
A sample googleAnalytics.ftl is included in the built-in theme. This file
serves only as an example, and you must replace the tracking code shown
with your institution's own tracking code.
For additional information about the GATC for the NIH-funded VIVO
implementation sites and a copy your institution's tracking code, see the
VIVO Google Analytics wiki page:
https://confluence.cornell.edu/display/ennsrd/Google+Analytics+for+UI
************************************************************************
5. If you had modified web.xml to configure the Pellet Reasoner (as described
in the installation instructions), repeat that modification.
6. Stop "Apache Tomcat" and run ant by typing: ant all
7. If you have set up the Apache Tomcat Connector using mod_jk and modified
your tomcat/conf/server.xml file, you will need to add a line to your
context section specifying a "Manager" tag; see examples below.
Context section before:
<Context path=""
docBase="/usr/local/tomcat/webapps/vivo"
reloadable="true"
cookies="true" >
<Environment type="java.lang.String" override="false"
name="path.configuration"
value="deploy.properties"
/>
</Context>
Context section after:
<Context path=""
docBase="/usr/local/tomcat/webapps/vivo"
reloadable="true"
cookies="true" >
<Manager pathname="" />
<Environment type="java.lang.String" override="false"
name="path.configuration"
value="deploy.properties"
/>
</Context>
8. Start "Apache Tomcat" and log in to VIVO.
-------------------------------------------------------------------------------
III. Ontology Changes
A. Verify Ontology upgrade process
After Apache Tomcat is started, these files should be reviewed to verify that
the automated upgrade process was executed successfully. The ontology alignment
process will create the following files in the Tomcat webapps/vivo/WEB-INF directory:
ontologies/update/logs/knowledgeBaseUpdate.log
a log of a summary of updates that were made to the knowledge base and notes
about some recommended manual reviews. This file should end with
"Successfully finished processing ontology changes".
ontologies/update/logs/knowledgeBaseUpdate.error.log
a log of errors that were encountered during the upgrade process. This file
should be empty if the upgrade was successful.
ontologies/update/changedData/removedData.n3
an N3 file containing all the statements that were removed from the knowledge base.
ontologies/update/changedData/addedData.n3
an N3 file containing all the statements that were added to the knowledge base.
B. Ontology knowledge base manual review
Changes to the VIVO core ontology may require corresponding
modifications of the knowledge base instance data and local ontology
extensions.
When Apache Tomcat starts up following the upgrade, it will initiate
a process to examine the knowledge base and apply necessary changes.
Not all of the modifications that may be required can be automated,
so manual review of the knowledge base is recommended after the
automated upgrade process. The automated process will make only
the following types of changes:
Class or Property renaming
All references to the class (in the subject or object position) will
be updated to the new name. References to the property will be
updated to the new name.
Class or Property deletion
All individuals in a deleted class will be changed to
belong to the nearest available superclass (which may be owl:Thing).
All statements using a deleted property will be changed
to use the nearest available superproperty. If there is no available
superproperty then the statement will be deleted from the
knowledge base. Note that all removed and added data
is recorded in the files in the changedData directory.
Class or Property addition
If a newly added class has a superclass and there are
individuals in that superclass, then a note will be
added to the log file suggesting review of those individuals to
see if they should be reasserted in the newly added class.
If a newly added property has a superproperty and there are
statements using the superproperty, then a note will be added to
the log file suggesting review of those statements to see if they
should be reasserted using the newly added property.
Annotation property default values
It a site has modified the value of a vitro annotation (such as
displayRankAnnot or displayLimitAnnot) so that it is
no longer using the default, then that setting will be left unchanged.
If a site is using the default value of a vitro annotation, and the
default has been changed in the new version of the ontology, then
the new default value will be propagated to the knowledge base.
-------------------------------------------------------------------------------
IV. New File Storage System
A. Verifying the File Storage upgrade
If, for any reason, the File Storage upgrade process is not successful,
VIVO will not start. Attempts to open VIVO in the browser will result in a
404 error. Tomcat's "localhost" log file will contain an exception listing
with more information.
The File Storage upgrade process will create these files in the Vivo upload
directory:
upgrade/upgradeLog.2010-00-00T00-00-00.txt
A log of the upgrade process. The actual filename includes a timestamp
that tells when the upgrade executed. This file should be inspected
for warnings or errors. The file should end with "File Storage update
is complete."
upgrade/translatedImages
Contains the images that were translated to the new file storage system.
upgrade/unreferencedImages
Contains the images which were in the "images" directory, but were no
longer referred to by any Individual.
file_storage_root
A directory where the uploaded images are stored. Within the root, the
path to the image is derived from its unique ID and its filename.
file_storage_namespaces.properties
Contains the URL prefix used when serving the image files.
B. File Storage changes
Changes to the File Storage system in VIVO result in new properties to describe
the relationships involving files, and a new directory structure in which to
store the files.
Uploaded files are stored in the VIVO upload directory, as defined in the
deploy.properties file. Previously, images were stored in the "images" folder
of the upload directory. Now, all uploaded files will be stored in the
"file_storage_root" folder of the upload directory.
Previously, image files were served from the images directory within the web
application, within Tomcat, and copied to the upload directory for backup
purposes. Now, image files are stored only in the upload directory, and served
directly from there. The image directory within the web application is no
longer used.
When Apache Tomcat starts up following the upgrade, it will initiate a process
which makes the required changes:
Initializing the file storage system
Each file will now be assigned a unique ID, in addition to its filename.
Both the ID and filename are used to store the file within the system.
Uploading two images with identical filenames will not cause a conflict.
Pruning dead image references
Previous versions allowed manual editing of file paths, sometimes resulting
in erroneous information. Any image properties that refer to non-existent
files will be removed.
Removing unreferenced images
Any uploaded image which is no longer referred to by an Individual will
be removed.
Generating main images and/or thumbnails
Each image will be represented by both a main image file and a
thumbnail image file. If either of these is missing for a particular
individual, it will be created.
Converting image properties on Individuals
Image properties previously were simple data properties, referring to
the filename and path. These are replaced by object properties, which
refer to the file by its unique ID.
Translating images into the new directory structure
Each image file will be copied to its new location in the upload
directory.
Cleaning the old image directory.
All image files are removed from their old locations in the upload
directory.
Once you are satisfied that the File Storage upgrade process is successful,
you may delete the "images" folder and the "upgrade" folder from the upload
directory. You may also delete the WEB-INF/images directory from within
your Tomcat web application.
-------------------------------------------------------------------------------
V. Theme Changes
VIVO 1.1 introduces the first step in a transition from JavaServer Pages (JSPs)
to the FreeMarker template engine for generating web pages. As part of this
process, the JSP files that were used for theme customization in earlier
versions of VIVO have been replaced by a set of FreeMarker templates.
In the 1.1 install package, these files are located in
/vivo/themes/vivo-basic/templates and have an ftl (for FreeMarker Template
Language) extension.
Follow step A or B below, whichever is applicable to your site:
A. If you did not create a customized theme for your site in VIVO 1.0, but used
the 1.0 vivo-basic theme in its original directory, you need not take any action
in order to convert your site to the VIVO 1.1 theme.
B. If you created your own theme directory in VIVO 1.0, follow the steps below
to upgrade your theme to VIVO 1.1.
1. Copy the directory /vivo/themes/vivo-basic/templates into your theme
directory /vivo/themes/<your-theme-name>.
2. Follow step a or b below, whichever is applicable to your theme:
a. If you did not apply any customizations to the JSPs in your VIVO 1.0
theme, then you do not need to apply any additional changes to the
VIVO 1.1 theme templates during the upgrade process.
b. If you did apply customizations to the JSPs in your VIVO 1.0 theme,
you will need to hand-replicate those modifications in the new theme
template files.
The theme template content that was previously contained in three
JSP files is now contained in five FTL files. The correspondence
between the 1.0 JSPs and the 1.1 FTLs is as follows:
identity.jsp => identity.ftl
menu.jsp => menu.ftl and search.ftl
footer.jsp => footer.ftl
googleAnalytics.ftl is a new file included from footer.ftl to
which you will add your site's Google Analytics Tracking Code
(see section II).
Because the FreeMarker Template Language uses many syntactic
conventions that will be familiar to template authors from JSP or
other common templating systems, the translation of your JSP changes
into the new FTLs should be relatively straightforward.
Consult the FreeMarker Template Author's Guide at
http://freemarker.org/docs/dgui.html and the Reference at
http://freemarker.org/docs/ref.html for complete documentation of
the syntax and available built-in constructs. Template authors need
not be concerned with the Programmer's Guide or Java API documentation.
c. Remove the jsp directory from your themes directory.
3. VIVO 1.1 includes changes to vivo-basic stylesheets. If you modified
styles in your VIVO 1.0 theme, you will not be able to simply copy the
1.0 stylesheets into your 1.1 theme, because you will then lose 1.1
style upgrades that your theme should pick up. Instead, you should
use the vivo-basic 1.1 stylesheets as a starting point, and manually
merge your 1.0 style modifications in as needed.
