Metacat is a flexible database storage system for XML formatted
|
23
|
documents. Metacat models the structure of the XML document, therefore
|
24
|
allowing storage of XML documents with arbitrary schemas. Metacat supports
|
25
|
several databases on the back-end, including Oracle, PostgreSQL and SQL
|
26
|
Server. The server supports XML document storage, retrievel, query,
|
27
|
validation, and transformation (using the XSLT stylesheet language).
|
28
|
In addition, there is a mechanism for replicating the database
|
29
|
to other metacat instances for backup and load balancing purposes.
|
30
|
Metacat currently uses an LDAP database for authenticating users, but
|
31
|
was written to accomodate other authentication services as well.
|
32
|
|
33
|
Release Notes
|
34
|
|
35
|
In this release, the structure of the xml_replication table was changed.
|
36
|
If you try to update a previously installed Metacat, you should run a script
|
37
|
file to updated the table structure before installation.
|
38
|
For Oracle user: At the SQLPLUS prompt type the following -
|
39
|
@src/xmlreplicationtable.sql
|
40
|
For Postgresql user: At install directory prompt type the following -
|
41
|
psql exp < src/xmlreplicationtable_postgres.sql
|
42
|
(where 'exp' is the database name).
|
43
|
|
44
|
If you are a new Metacat user, this step is unneeded.
|
45
|
|
46
|
The build.xml file now has a property named datafilepath. It should be set
|
47
|
to the location of where you want your data files stored. If you are an
|
48
|
existing user, this directory should be /<tomcatdir>/webapps/metacat/data
|
49
|
where <tomcatdir> is the your tomcat installation directory where
|
50
|
your webapps directory is located and 'metacat' is the name of your servlet
|
51
|
instance.

New features in 1.1.0:
|
76
|
1) Added functionality to export a zipped data package. The zip file contains
|
77
|
all of the data and metadata as well as a rendered html summary of
|
78
|
the metadata.
|
79
|
2) Changed version control mechanism. Metacat can now accept any version of
|
80
|
a document as long as the given version number is greater than the
|
81
|
current one. The new version number does not have to be exactly one
|
82
|
greater than the current version.
|
83
|
3) Update xerces.jar file to version 1.4.4
|
84
|
Fixes in 1.1.0
|
85
|
1) Fixed ldap authentication bug. Now, a user from a referred server cannot
|
86
|
login with an incorrect password.
|
87
|
2) Changed the default behavior of the access control functionality with
|
88
|
respect to packaging.
|
89
|
If a member document in a data package doesn't have an access control list,
|
90
|
access control rules of the main package document will not apply to the
|
91
|
member document. Previously, package members, by default, inherited
|
92
|
the access control rules of the main package document.
|
93
|
3) Fixed minor bugs with document access control.
|
94
|
4) Allowed new version of data files to be uploaded and handled.
|
95
|
5) Fixed bug where the client could not get the principals or groups from
|
96
|
the ldap server.
|
97
|
Fixes in 1.0.3
|
98
|
1) Fixed problem with Metacat not being able to query for group names when
|
99
|
and LDAP referral server was down. Added an LDAP timeout of 5 seconds
|
100
|
for all referral activity.
|
101
|
2) Fixed problem where invalid xml characters such as ampersands (&) could
|
102
|
be inserted into the resultset xml stream.
|
103
|
Fixes in 1.0.2
|
104
|
1) Fixed problem with LDAP locking up Metacat when a referral server
|
105
|
was not available.
|
106
|
Fixes in 1.0.1
|
107
|
1) Fixed problem with authenticating using LDAP referrals
|
108
|
2) Fixed bug that prevent groups from being used in access documents
