|
* Here is the rules for user which has write permission in top level access
|
56 |
|
|
* rules(he can update metadata but can't update access module) try to update
|
57 |
|
|
* a document:
|
58 |
|
|
* 1. Checking access part (both in top level and addtional level, node by node)
|
59 |
|
|
* If something was modified, reject the document. Note: for additional part
|
60 |
|
|
* The access subtree startnode starts at "<describ>" rather than <access>.
|
61 |
|
|
* This is because make sure ids wouldn't be mess up by user.
|
62 |
|
|
* 2. Checking ids in additional access part, if they points a distribution
|
63 |
|
|
* module with online or inline. If some ids don't, reject the documents.
|
64 |
|
|
* 3. For inline distribution:
|
65 |
|
|
* If user can't read the inline data, the empty string in inline element
|
66 |
|
|
* will be send to user if he read this eml document(user has read access
|
67 |
|
|
* at top level - metadata, but user couldn't read inline data).
|
68 |
|
|
* Here is some intrested senario: If user does have read and write
|
69 |
|
|
* permission in top level access rules(for metadata)
|
70 |
|
|
* but 1) user doesn't have read and write permission in inline data block,
|
71 |
|
|
* so if user update the document with some inline data rather than
|
72 |
|
|
* empty string in same inline data block(same distribution inline id),
|
73 |
|
|
* this means user updated the inline data. So the document should be
|
74 |
|
|
* rejected.
|
75 |
|
|
* 2) user doesn't have read permssion, but has write premission in
|
76 |
|
|
* inline data block. If user send back inline data block with empty
|
77 |
|
|
* string, we will think user doesn't update inline data and we will
|
78 |
|
|
* copy old inline data back to the new one. If user send something
|
79 |
|
|
* else, we will overwrite the old inline data by new one.
|
80 |
|
|
* 4. For online distribution:
|
81 |
|
|
* It is easy than inline distribution. When the user try to change a external
|
82 |
|
|
* document id, we will checking if the user have "all" permission to it.
|
83 |
|
|
* If don't have, reject the document. If have, delete the old rules and apply
|
84 |
|
|
* The new rules.
|
85 |
|
|
*
|
86 |
|
|
*
|
87 |
|
|
* Here is some info about addtional access rules ( data object rules):
|
88 |
|
|
* The data access rules format looks like:
|
89 |
|
|
* <additionalMetadata>
|
90 |
|
|
* <describes>100</describes>
|
91 |
|
|
* <describes>300</describes>
|
92 |
|
|
* <access>rulesone</access>
|
93 |
|
|
* </additionalMetadata>
|
94 |
|
|
* <additionalMetadata>
|
95 |
|
|
* <describes>200</describes>
|
96 |
|
|
* <access>rulesthree</access>
|
97 |
|
|
* </additionalMetadata>
|
98 |
|
|
* Because eml additionalMetadata is (describes+, any) and any ocurrence is 1.
|
99 |
|
|
* So following xml will be rejected by xerces.
|
100 |
|
|
* <additionalMetadata>
|
101 |
|
|
* <describes>100</describes>
|
102 |
|
|
* <describes>300</describes>
|
103 |
|
|
* <other>....</other>
|
104 |
|
|
* <access>rulesone</access>
|
105 |
|
|
* </additionalMetadata>
